Kouki Doesn't Commit Suicide

"Cats Don't Laugh". After escaping the Aoyama Pharmaceuticals lab, Kouki wonders if he is in fact one of the clones that were created there, and what to do with himself next. Rin hands him a pistol and tells him it's up to him whether he lives with the pain, or chooses not to. She returns to the truck, and we hear a gunshot. However, later, back at her and Mimi's office, Kouki shows up with his head bandaged: apparently he jerked the gun aside at the last moment and only grazed himself, and states that whether or not he's a clone, he's the only one who can live his life, and asks them if they're hiring.
