Catstiel and Dean have the most of the same classes throughout the day, they got to know each other pretty fast through out the day. It was Thursday and they had out Friday. Later when they where leaving school Dean invited Castiel to come over to his place after school.

"Yeah my dads out of town on business, and the only other person in the house would be sammy, my little brother."  Dean had a guilty look in his eye for lying to his friend, but quickly vanished when Castiels eyes jumped to him from the sidewalk.

"Oh okay Dean would you like to pick me up, or shall we just head towards your house now?" Castiel could tell Dean was lying about something, and were would his mom be? He decided not to press and just went with it. 

"Oh, um, yeah, we can go now, but I have to pick up Sammy." "Not a problem." Castiel replied.
