The Uninvited Guest

The wedding march music is starting to play at a church

Inside, Tommy is at the alter, he turns his head and sees Gaz, his bride, walking towards him. Her veil is over her face. Her father is walking with her. Then he lets her go and takes a seat.

The minister smiles. "Dearly beloved, we are gathered here today to see the union of these two. If anyone here has a reason why these two should not be married, speak now or forever hold your peace?"

No one spoke

"Gaz Membrane, do you take this man, to be your husband?" He asked.

"I do?" Gaz smiled.

"And do you, Tommy, take his woman to be your wife?" He asked.

"I do." Tommy smiled.

The rings were handed to them. They each put them on the others fingers.

"You may now, Kiss the bride." The minister smiled.

Tommy moved the veil off and the two kissed.

"Ok! That's good enough for now!" A voice called out.

Turns out this was all a recital. Gaz had just the veil on, no dress or anything else, just her usual outfit. Everyone, all of their friends and family, applauded.

Tommy and Gaz blushed.

Prof. Membrane smiled. "Come on now, lets all head over to the restaurant for dinner."

Tommy and Gaz sighed with relief.

"Nice save dad." Gaz whispered to him.

All of the girls went with Gaz, while all the guys went with Tommy.

However, unknown to them, a mysterious spy-bot was spying in on them.

Elsewhere

At a strange lab of some sort, a green skinned being is looking at the two.

"Grr...Gaz, I do not know why you've chosen that earthling. He cannot be worthy to one such as I. I will prove that no one can have you. NO ONE!" He yelled.

A weird robot with Green Eyes just stares.

Back in the Girls hotel...

The girls are hanging out at Gaz's apartment with Tommy not in sight (it was known that it's bad luck for the groom to see the bride before his wedding so he's staying at his parents for a while).

"Man, we envy ya Gaz. Any one of us would want Tommy as a boyfriend for his work on the best movie ever." Lil said.

"Not me. I'm his cousin remember." Angelica reminded everyone.

"She didn't mean you, Angelica." Susie said with a sigh.

"Man, I betcha you and Tommy are excited about the big day, huh?" asked Kimi with a smirk.

"Oh, I am. But I'm worry." Gaz said with a sigh.

"Why should you be? You're going to marry Tommy." Kimi said a bit surprised.

"Well, I'm afraid something would happen that would either destroy or messed up the wedding." Gaz admitted.

"Come yourself, girlfriend." Kimi said patting her friend on the back. "What's more to worry about? I am dating Timmy Turner now, your brother agrees to lay off the alien stuff during the wedding, Tommy isn't scheduled to do any film stuff, and everything is mellow. What else could go wrong?"

"I could you're right."

"Come on. Are we going to do something or are we going to bored ourselves?" asked Lil bored.

"How about video games? I'm going to beat you all." Gaz said with a smirk.

"Sez you!" laughed Susie.

At the guys' hotel, Tommy is hanging out with the guys.

"Man, I hope things goes well in time for the wedding. I'd been looking forward to this all my life." Tommy said with a sigh.

"Remind you of anyone, Dil." Phil told Dil with a smirk.

"Shut up." Dil told Phil.

"Well, at least you got a few days of being a bachelor before you're married to my sister. So how about we celebrate?" asked Dib.

"Okay, but two things. No alcohol or strip people. We don't want Gaz to be ticked off at Tommy." Chuckie told everyone.

"Or Kimi at me." Timmy Turner added, remembering he is still with Kimi.

"Man, with things turning out right, what could go wrong?" asked Tommy.

Tommy should have known that he should never say that.

The next day is the day of the wedding

Inside the bride's dressing room, Kimi, who is the brides-maid, is helping Gaz with her wedding dress. It is a black colored, rather gothic looking dress that kind of had a vampires-twist to it.

"I can't believe you actually got someone to make that dress from your designs." Kimi said. Gaz had difficulties getting people to make her dress because as soon as they found out it was black, and not white, most of them refused right away.

"Well, it's a good thing we waited until we got here to New York to find a dress-maker who would do it." Gaz smiled.

"Yeah...and another thing. WHY New York?" Angelica, who was nearby, asked.

"Oh, I don't know. I always wanted to go to the Big Apple and I figured that it just seemed right to have the wedding there, away from all those movie people who would had bothered us if we followed Tommy's Hollywood-wedding suggestion." Gaz replied.

"Say, Gaz, the only people from your side is just your father and brother and that weird, tall, thin old lady. Who is she anyway?" Lil asked.

"Her? Oh she's my brother's old teacher Ms. Bitters. I just invited her here because, besides my dad, brother, and me, she was the only other actually smart person from my town. That is if you ignore her rambling and yelling." Gaz replied. Then a smirk came across her face. "Besides, I knew it would drive Dib nuts if she was here."

Elsewhere in the church

Dib is greeting people inside. Just then someone or something slithered up to him.

"Dib!" She yelled.

Dib jumped and, slowly, turned around. "Oh! Ms. Bitters! How nice to see you!" He said nervously.

"What are you doing here? Planning on ruining your own sisters wedding with all your alien rambling!" She snarled. Ms. Bitters never liked any student she's had, until she later got Gaz in her class. Gaz was the only student Ms Bitters respected.

Dib shook his head fast. "Eh...no Ms. Bitters. I promised her I wouldn't dare do such a thing."

"Good." Ms. Bitters said coldly. Then she looked out into the main area. "You know I went to a wedding once."

Flashback

A younger Ms. Bitters was walking down the aisle dressed as a flower-girl. Suddenly one of the candles nearby fell, lit the end of the trail of flowers, and, like a fuse, the flames moved all the way to her and set her on fire. She ran around and around.

End of flashback

Dib shivered nervously.

Elsewhere

Tommy is in the Grooms dressing room, his dad is there helping him with his tie. Grandpa Lou and Uncle Drew and the rest of the guys were there too.

"There you go champ." Stu smiled. "You ready?"

Tommy shook his head. "Not really dad."

"Hey, cheer up Tommy." Drew smiled as he looked at his nephew. "You're getting married to a great girl, you're having a great movie-making career going for you already, and you have the support of all your friends and family."

Prof. Membrane put his hand on Tommy's shoulder. "And my Daughter is definitely one of a kind. Although I never paid much attention to her as she was growing up, I can tell you that she really has changed since she's met you. Why I can't even beginning to remember how many times she's caused Dib pain or problems. However when you came into her life, I can already tell you she's changed for the better."

"Yeah I know." Tommy sighed. "It's just...Marriage seems so...so...final."

"Now listen here sprout." Grandpa Lou said as he came up to his grandson. "Marriage may seem final but it's not, it's a whole new beginning. Once you're married, you have a whole world of new things opened up for you. Like kids, grand-kids, your first home, everything."

Tommy smiled. "You're right Grandpa."

Chuckie walked up to Tommy. "Thanks for having me be the best man."

"Of course, who else would I give that job to? You're my best bud." Tommy smiled.

Chuckie nodded.

Stu looked at the clock. "Oh, come on now champ. It's almost time." With that, everyone got into their places.

Later

Everyone starts to walk down the aisle into their seats. Soon everyone is there, except Gaz and her father. The organ starts to play "Here Comes the Bride". Tommy turns to see Gaz in the most beautiful dress he's ever seen her wear. He is rather jaw dropped.

As they're coming down, Membrane whispered to his daughter. "You look lovely Gaz dear."

"Thanks dad." Gaz smiled.

Then Prof. Membrane let her go and took a seat.

Tommy and Gaz looked at each other happily.

The minister cleared his throat. "Dearly beloved, we are gathered here today to see the union of these two. If anyone here has a reason why these two should not be married, speak now or forever hold your peace?"

Suddenly there was a huge explosion that made a huge hole in the wall. The shockwave knocked some people back, and Gaz into Tommy's arms. They all looked up to see a rather tall, green skinned creature with Spider-legs that seemed to come out of a pak on his back, come out of the hole.

"I object." He snarled.

"Zim." Gaz gasped.
