"Hey Cas! Wait up!" Castiel heard a voice as he walked his usual route to school, Monday morning. It seemed like it took months for the day to even turn. He had spent the whole weekend at the Winchester house which whenever he thought about it made a spring of happiness warm his heart. He stopped allowing Dean to catch up. "You seem a bit out of it, the Green Bitch still freaking you out?" while watching the Wizard of Oz with the Brothers, Dean had discovered and found extremely amusing how uncomfortable the Munchkins and Wicked Witch had made Castiel. "No, but I would prefer that I never have to watch that movie. Ever. Again." He punctuated each word with a scowl as Dean just laughed. They walked in silence as Castiel replayed the events of the weekend, he had had fun that was for sure but what had happened between him and Dean in the Garage still weighed on his mind. He had wanted to question Dean about it but had no idea what to say. "Something's bothering you, what is it?"

"Nothing, I am just pondering what we may have to do in Detention today." Dean snorted as his phone buzzed. "Yeah about that Cas, I need you to cover for me."

"Cover for you?" Dean pulled Castiel aside away from the other students and teachers who might possibly be listening into their conversation. "Yeah, promised Lisa I would meet her over school." A dark emotion replaced his happiness at the sound of the name. "Lisa? I did not realise you were dating." The words came out stonily which thankfully Dean did not picked up on. "Couple weeks now, so will you cover for me?" Castiel bit his lip completely uncomfortable with the idea of lying. "I-I would not know what to say." With a smile Dean pulled Castiel closer. "Easy just say 'Dean's had to leave because of a Family Emergency.'" There was a pulse beat wait as Castiel tried to make a decision. "What if they do not believe me?" his voice became quiet. "Well I won't be there so it won't matter and I'll just tell them the same thing if they asked me. C'mon man I would do it for you." Dean squeezed his shoulder in anticipation, Castiel's heart pumped wildly and painfully in his chest. "Okay." At the word Dean smiled which instead of making him feel good about his decision of helping a friend, it felt like a rock had fallen into the pit of his stomach. "I owe you man!"

The feeling of dread about the upcoming lie stayed with Castiel the entire day and he soon became aware of Dean's relationship with Lisa. He walked around school with Lisa at his side and barely acknowledged if their paths crossed. "I don't know what he sees in her." Chuck had noticed Castiel watching the couple from a distance. "She's not exactly the nicest person around." Castiel pushed his lunch aside as he saw Dean press a kiss on Lisa cheek. "Does it bother you?" he felt the similar strong urge to confide, he could trust Chuck. "It does, but it is something else which bothers me more. Have you ever had to cover for a friend?" Chuck tore a part his sandwich while nodding at the same time. "Yeah once or twice. Why?"

"I have agreed to 'cover Dean' so he can meet her after school." He saw understanding on Chuck's face immediately. "And you're not comfortable with lying?" a sense of relief filled him as he silently thanked the Heavens that Chuck understood. "I am worrying that the teacher will not believe me." Chuck patted Castiel's arm. "They'll believe anything with the words 'Family Emergency.' Trust me they won't even think twice."

The rest of the day had dragged until finally he walked towards the Gym only to find out that someone had already reported Dean's 'Family Emergency.'

"Don't look so relieved Novak but since I'm feeling generous you can have this one off. I'll see you tomorrow both you and Winchester will have to make up the time. Pass the message on when you see him next."

As Castiel walked home he had come to the conclusion that Chuck may have been responsible for telling the teacher about Dean's 'Family Emergency.' He walked up the road to Dean's house without even thinking and was greeted by Sam who was sitting on the front yard writing in his notebook. "Dean's not in at the moment." Castiel regarded the boy whose green eyes were filled with annoyance. "I see, I will come back later when he returns." He made to leave only to have Sam grabbed him by his sleeve. "Could you keep me company? I don't like being alone in the house." He sat down next to the Younger Winchester who closed his notebook. "Do you know where he has gone?" he saw a look of distaste take its place on Sam's face. "He's with Lisa, I don't like her." Castiel stared in surprise at Sam's outburst. "Why?" Sam tapped his fingers on his knees. "Promise you won't tell?" he nodded. "Well I asked if they wanted to watch a movie with me so I wouldn't get lonely, and she got fussy about it being a waste of time." By his tone that had annoyed Sam a great deal. "Did Dean not say anything?" An air of sadness took it places in Sam's eyes replacing the annoyance. "No and he always would but with her he's different. It's like when he's with her he doesn't care about other people's feelings and would do anything to please her."

Castiel found himself relating to Sam on the basis of them both being the Little Brothers of a Family. "I mean he would always defend me no matter what if someone was bullying me but with her it's truly like he doesn't care." The statement itself angered Castiel, from the way Dean interacted with his Little Brother on Saturday he saw the same actions that Gabriel showed whenever he had protected him. "Because Dean always said that Family comes first no matter what." Another flare added to the anger boiling in his body as Sam carried on. "He's kinda gone back on his word."
A small hiccup escaped Sam as Castiel patted his back awkwardly in the effort of trying to comfort him. "Dean told me you're the Younger Brother too right? So I can kinda guess you get what I'm saying right?"
Castiel closed his eyes briefly remembering the feeling of betrayal both Michael and Raphael had done to him but the love he felt for Gabriel when he had protected him from their Father's rage. "Yes, the bond between Brothers is strong."
"Would your Brother ever abandon you?" he stared at the Younger Winchester it was one of the questions he had least expected to be asked, he looked at his shoes trying to find the best way to answer the question.
"Gabriel would never abandon me although the same cannot be said for my other Brothers. Gabriel made a promise to protect me no matter what and he is not the kind of person to break them."

Castiel stayed with Sam as time passed it became increasingly clear that Dean was not going to come back for night which soon distressed Sam, from the lack of communication between the Winchester Brothers. "I don't think he's coming back." He saw a very familiar twitch of the lips which struck a cord in Castiel's memories. Sam was trying to hold back his tears and keep strong. "Do you have anywhere you can go or would you like to stay at my house for the night? I'm sure Gabriel will not mind the extra company."

"Thank you but I'll give my Uncle Bobby a ring and stay with him for the night." He left his place on the yard returning with his eyes ringed red which only aggravated Castiel's annoyance and anger towards Dean Winchester actions. "He's on his way and is not happy, he's probably gonna rip Dean a new one for ditching me. Thanks for staying with me Cas I wish I had a Brother like yours at least you can depend on him."

A/N: Angry Cas. Oh Dear. That's not going to end well with Dean (Remember what happened last time when Dean pissed of the Nerd Angel?), but I don't think he's going to beat him up though... Well not physically anyway.
Reviews are awesome :) And I've only missed my 3am deadline by 31 minutes, haha!
