I'm looking for a(nother) fic where I believe the whole cast are out clubbing, but at least Chris and Cory. Cory notices that Chris is acting strangely, and gets him away from the guy hitting on him. He thinks Chris has been drugged, and there were subsequent chapters where Chris had to go to the hospital to be tested, and him freaking out about what could have happened.
I could be wrong about it being Cory, though I don't believe so. I also think it was heading to Cory/Chris slash, but it was definitely in the friendship zone when I read it.
It was a WIP, but I can't think where it was posted, and would greatly appreciate being able to read it again. Thank you for your help!
ETA: Found, thank you! Link in comments.
