People have been asking me to do a sequel for Shaggy's secret. I had intended to do it but I am trying to finish my other stories first. However the ideal will not leave my head. So here it is. It will be a longer fic and it takes place two years after the last story ended. I own nothing.

Lilly was created by Littlebixuit. She is a talented writer and allowed me to use her character. Something I will always be grateful for.

Chapter one

It had been two years. Two years since Thorn and Shaggy revealed to the members of Mystery Inc and the Hex Girls that they were dating and were in love. Yes Daphne and Scooby knew but neither told. Luna and Dusk knew Thorn was dating someone but did not know whom it was. All they knew was that she was happy and the one she was dating respected her.

It had been two years since Shaggy and Scooby left mystery Inc. During that time as Daphne had predicted the gang did not do well. They tried a few mysteries without Shaggy and Scooby but they failed badly. The first couple seemed to be doing well but the last one they solved the mystery but it was not right there was a lot of fighting amongst the remaining members.

Daphne found out that Fred was cheating on her. After nearly killing him Fred had not been heard from since. Velma went back to working for NASA after a break up with Patrick. Daphne called Shaggy the night she discovered the betrayal and started crying. Thorn, Luna and Dusk convinced her to join them on the tour. She performed with them once as Crush and become her once more. (Yes I know how the series ended but work with me by the way it sucked good series expect the last episode I mean come on we are the heart really people. Anyway off topic.)

As for Shaggy he was beyond happy. He had a great relationship with a woman he loved. She was famous yet still down to earth. She was smart, funny and beyond beautiful. There were many times that he felt he was unworthy of her. Thorn had to smack him to get him to see that he was worthy. He finally saw that she loved him and he loved her and that was all that mattered. He sometimes still thought Thorn could do better than him but he never voiced his thoughts.

Scooby on the other hand was happy to see his master so happy. Scooby was happy when the relationship between Shaggy and Thorn grew. You see both humans had a secret. This was a few weeks ago and as the tour was coming to a close. The two told each other there secret. For Thorn only one person knew her secret and that person was her mother. However her mother died when she was young. Her father never knew and he went to his grave not knowing it. Thorn never regretted not telling her father. She knew her father would react badly.

Shaggy on the other hand only Scooby, Scrappy and one of his ex's knew as well as six others. Scrappy was in prisoner for trying to kill Shaggy and the others. His ex well it is best not to talk about her. Even if she told the secret no one would believe her. Besides there were times she wondered if it was true or not. The six others were often looked upon as outcast and they trusted and respected Shaggy too much to tell his secret. Shaggy recalled the day they told each other their deepest darkest secrets.

Flashback.

Thorn was nervous no actual she was past nervous. Shaggy could tell right away that she was nervous. He could feel it coming off of her. Shaggy pulled her into a hug which caused her to relax. She said. "Shaggy there is something I need to tell you. If you want to break up with me after I tell you I will understand." Now Shaggy was really worried for her.

Thorn said. "Shaggy there is no easy way to tell you this. Right now you will be the only one that knows. My mother knew but she died. I never told my father. Not even Luna and Dusk know this about me." She took a long pause before saying. "I am a Witch a full blooded Witch." Shaggy said. "Ok why would you think I would want to break up with you? I do not for the record. I do not care that you are a witch."

Thorn said. "Why? I thought you disliked all monsters and that is what I am?" Shaggy said. "No my princess you are not a monster. I know some real monsters and I have a secret as well." He closed his eyes and allowed the transformation to take shape. After a few seconds Shaggy was covered with fur and had bright yellow eyes. He said. "I am a werewolf. Count Dracula turned me into one and I was never fully able to get rid of him. I can change at will." He changed back to his normal self.

Thorn said. "I was always a witch. My mother was one as well and she helped train me in using my powers. I hid them since I am afraid of how the world will react. When you first meet me and screamed witches I thought you had figured out my secret so I was scared. Your friends what they saw was witchcraft."

Shaggy said as he pulled her closer to him. "I do not care that you are a witch. I understand what it is like. I have some friends of mine that many consider monsters but are the nicest monsters or people you will ever meet. One has adopted me as her big brother."

Thorn said. "Can I meet them?" Shaggy said. "They would like that. My sister is really looking forward to meeting you. I will call them and see if we can visit." The two then shared a deep and loving kiss. Thorn and Shaggy both felt better now that they have shared their secret with the other.

End Flashback

True to his word Shaggy called Sibella who was the headmistress of the Ghoul School. Miss Grimwood sadly passed away a few years ago. She left the school to her original five students and the five took it over and made it better.

Sibella said. "My friend how are you doing?" Shaggy said. "I am doing very well. I was wondering there is someone that wants to meet you guys." Sibella smirked on the other side of the phone line and said. "So we can finally meet your girlfriend. It is about time. Don't worry I will not let Lilly hurt her."

Shaggy said. "Thanks my friend you are the best." Sibella responded by saying. "I know I am the best friend you have." After Shaggy hung up SIbella called all the girls together including Lilly. She said. "I have good news my friends. Shaggy will be coming in a few days. He is bringing his girlfriend the one we have been hearing about."

Lilly smirked and started to rub her swords. Sibella said. "Lilly you are not to attack her." Lilly said. "Why not?" Sibella said. "Simple Shaggy really cares about her and he would not bring her to meet us if he did not think she could handle it. So I am guessing she is powerful in her own right." She paused and smirked and said. "Plus he will be very sad if you hurt her. You may test her but do not actual harm her." Lilly pouted but agreed. She wanted to make sure the woman in question would not hurt her brother unlike Velma.

A couple of days later Shaggy and Thorn were at the Ghoul School. Shaggy warned Thorn that the people there were different he did not out right tell her who they were. He had promised and he never broke a promise. Thorn understood this and trusted Shaggy. She knew Shaggy would never put her in harm's way.

Before they walked into the school Shaggy said. "If you see a girl with two swords that is the one that claimed me has her bother. She is very protective of me so she may try to test you. She really wants to be left alone in a room with Velma for a while." Thorn asked. "Why does she have swords?" Shaggy said. "I gave them to her."

As the two walked in a bat landed on Thorn's shoulder. Thorn noticed that the bat was purple and the bat was looking at her in the eyes. Shaggy said. "Bella please be nice you did promise." The bat landed on the floor and in its place was a young woman with long purple hair and bright green eyes. She was smirking.

She said. "I did promise but I can have some fun and I was not going to bite her." Shaggy raised his eyebrows. SIbella said. "Ok I was going to bite her it is the best way for me to tell peoples intentions by tasting their blood." Sibella bowed before Thorn and said. "I am Sibella the daughter of Count Dracula and I guess the vampire princess. I am also one of Shaggy's sisters."

Thorn said. "I thought Lilly was his sister." Sibella said. "We are all his sisters but Lilly takes it further I guess. It is hard to explain but it works. I am surprise you are not freaked out that I am a vampire." Thorn said. "Shaggy trust you and I am Witch and Shaggy is a werewolf so I do not care."

Sibella smiled and said. "Shaggy I like her I like her a lot. I see what you said about her. She has a good heart. Do not let her go or I will kill you my friend." Shaggy said. "I agree but I do not think I would be that stupid to let her go without a fight." Sibella smiled and hugged Shaggy.

Sibella showed them around ok she showed Thorn around. She said. "Winnie is teaching right now and she needs some help. Some of the girls are giving her a hard time. Shaggy can you help out?" Shaggy had an evil smirk on his face. Thorn knew that smirk and knew it well. Thorn said. "I am watching it is always funny when you have that smirk."

Sibella said. "I agree he is going to scare the girls." She walked up and said. "Hello girls." She got back a chorus of hello headmistress. She then said. "Ok everyone today a special guest is going to teach you. He has taught me and the rest of the staff. He is a good friend of mine and like my brother. Also I warn you he can be scary when he wants to be."

A large werewolf bigger taller than Winnie stepped up and said. "Hello girls welcome to pain. For the next hour you will be in pain. Now I have a contest for you. The one that can last the longest will win." He looked at Thorn and she nodded her head. Shaggy said. "The prize is a poster signed by the Hex Girls."

At this all the girls started to cheer. This of course caused Thorn to sweet drop. The female werewolf that she saw before started to sniff Thorn. She said. "I like her. I am also surprised none of the girls noticed you are here. Your music is very popular at the school." Thorn said. "Of all that I have seen today that shocks me the most. Being in a school where the headmistress is a vampire and the gym teacher is a werewolf does not shock me." She took a pause before saying. "Having the girls of said school, that are all monsters like my music does. Not even the students being monsters shocks or worries me."

Winnie started to howl with laughter and I mean howl. She then said. "I like you. You got sprit I like that. I must warn you hurt Shaggy and your body will never be found." Thorn smiled and said. "I understand and I will not hurt him." Winnie smiled which was rare and said. "I know I can sense you have a good heart. I can also sense your power."

Meanwhile the girls had passed out all expect two. Thorn said. "Do I even want to know what he made them do?" Sibella smiled and said. "You have heard about basic training for the Marines just times that by 10 and that is light for him. This he only does when he is in a good mood."

After about three minutes another girl passed out. Only one was standing and she was having a hard time doing it. Shaggy handed her a rolled up poster. He then woke up all the girls and said. "If I hear that you are bugging my sisters then I will be back. All of your teachers are like my sisters." He took a pause and said. "By the way that was light wait until your see heavy." He then turned back into his human form and walked off.

Sibella said. "No matter how many times I see that it still scares me." Winnie said. "Ok girls that is enough for today. Be warned Shaggy trained me and taught me a lot of his tricks. See you all back here in a few days." So the four kept going and heard an explosion. Thorn was freaked out but the others were not.

Shaggy said. "Why did you give her the chemicals?" The vampire princess sighed and said. "She begged and it was easier and safer or else she would have made them herself." Shaggy said. "Elsa is the science teacher she enjoys explosions. She says she is improving the world but her experiments are often violent and involve explosions."

Thorn said. "So why allow her the chemicals?" Winnie says. "She will find other ways that are often more dangerous. So we have made a deal with her. We give her the stuff and she does it in a safe vault like area we set up for her."

Thorn said. "So bottom line you give in and allow her to do it safely or else she will do it and cause untold amounts of damage." All nodded at that. Thorn said. "Can I wait to meet her? She sounds like she is having fun." Sibella laughed and said. "Sure."

The gang heard some music playing and when they got to the source they found a woman that was transparent and blue and she was playing the piano. Thorn was smiling the woman was so into the music that she had not noticed anyone was there. Thorn understood that for it happened to her quite a bit.

When she was done playing which to Thorn was very wonderful. Everyone started to clap. The woman turned around and smiled when she saw Shaggy. She said. "It is good to see you again brother. Is this your girlfriend if she is I am very mad for you did not tell me your girlfriend is Thorn. You know I love the Hex Girls. "

Shaggy backed away and said. "I got you this." He handed her a poster that was signed by all the Hex girls. The woman smiled and said. "This makes up for it." She turns to Thorn and says. "It is an honor to meet you. I am a huge fan of your music. My name is Phanny I am the daughter of the phantom."

She took a pause before saying. "I have ways of making people do things they do not want to do. So if you hurt my brother I will make sure you do that." Thorn smiled and said. "I understand it is nice to meet a fan." So the other went off to another part and they find what looks like a hospital wing.

Thorn sees a tall woman covered in bandages and she has bright yellow eyes. She looks up hugs Shaggy and says. "I am glad to see you brother do you need any healing?" Shaggy said. "No I am fine. I feel great." The woman looks at Thorn and says. "A witch I have not seen a witch in a long time. You have great power that will not stop me from hurting you if you hurt my brother."

She paused and said. "I am Tanis the daughter of the mummy and the mistress of the healing arts." Thorn said. "I understand and I will not harm your brother I promise you." Into the room walks a really tall woman with black hair and green skin. She has two blots coming out of her neck. She is also covered in burn marks.

She sees Shaggy and gives him a bone crushing hug that actually crush's bones. Tanis heals Shaggy bones. The woman then hugs Thorn and says. "Don't hurt my brother or I will crush you. I am Elsa the daughter of Frankenstein." Tanis healed Elsa and the gang moved to the last stop before the mess hall.

They heard the sound of metal hitting wood and other sword sounds. Thorn said. "Is that Lilly?" Shaggy answered his girlfriend by saying. "It is a good bet." So the gang walked into the room and saw a girl training with two swords. Both were about four inches long and had a red hilt.

The girl was her height but had brown hair on her body. She had whiskers on her face and a long tail. Her eyes were a yellow color. They were looking at Thorn. With great speed she charged at Thorn and attempted to cut her in half with her twin swords. Quicker than anyone could see Thorn blocked the swords with a shield of air. She used the same air to push the girl back.

Lilly started to laugh. After she was able to calm down she said. "It seems my brother has found a powerful mate. Be warned if you hurt my brother the same way the four eyed one did I will end you." Thorn walked over to the young girl and hugged her. She then said. "I will never hurt you brother he means too much to me."

Lilly said. "I know it is just hard to lose my brother and to see him with someone. I never had anyone that cared for me until he rescued me and brought me to this home. So a part of me feels like I am losing him." It was only Thorn and Lilly in the room.

Thorn said. "Well I can tell you this you will not lose your brother he cares about you too much. Family is the most important thing to him." Lilly asked. "What if you are married and he has kittens of his own?" Thorn said as she pulled the young girl into a hug. "He will still love you and be in your life."

Thorn took a pause and said. "He speaks a lot about you and all of his sisters so he will always be in your life." Lilly smiled and said. "Thank you I need to tell you something. I know I call him my brother but I see him as a father." She then looked with hope filled eyes as she asked. "Does that mean you will be my mother?"

Thorn blushed at this and said. "If we are married then yes I will be your mother." Lilly said. "He loves you it will happen. I see it in his eyes. Now come on." The two got up and left to go to the mess hall. Thorn thought about the young girls comments. She wondered what it would be like if she was married to Shaggy and had children or kittens of her own.

She blushed at the thought but she found herself enjoying the idea. Lilly smirked and said. "I see you like the idea." Thorn said. "Yes I do but I do not know when it will happen." Lilly said. "Neither do I. I just know it will happen I can feel it. If you hurt him I will kill you even if I die in the process."

Thorn smiled she saw the loyalty the cat girl had for her boyfriend. She saw that Lilly loved Shaggy as a father. The two headed down to the mess hall to eat. Shaggy apologized for leaving her alone. Thorn told him it was ok and that she was not mad at him. This in turn caused Shaggy to feel a lot better.

During dinner Lilly was talking to Shaggy. She said. "Brother I think she is perfect don't let her go." Shaggy smiled and said. "Don't worry I have no intention of doing that. She finish's up her tour in a few weeks. After that I have a plan don't worry if all goes well she will be a mother figure for you." Lilly was shocked that Shaggy figured it out.

Shaggy said. "I know you see me as a father. I was nervous since I did not know if I could be a good role model for you." Lilly threw herself at Shaggy and started hugging him tightly. She said. "I don't care you treat me like a daughter and have since you saved me. I love you daddy." Shaggy found her when she was really young like four or five years old. So it made sense that she saw him like that.

Lilly said. "I only called your brother because I did not want to lose you." Shaggy said. "I promise little one you will be like a daughter to me even when I have children of my own." Lilly threw herself at Shaggy hugging him tightly saying. "I love you daddy." Thorn looked on at this and smiled. Shaggy would indeed make a great father.

After heavy goodbyes the two left since Thorn had another show to do in a few hours. Thorn asked. "Why did you not tell me she thought of you as a father?" Shaggy said. "I did not want to worry you that and I was unsure." Thorn smiled and said. "Well I think it is cute you will make a great father someday." Shaggy of course blushed at this.
