You were Angel Dust's freind since you were both alive.You also live at the hotel with him,rent free after all and you help him with his injurys after he comes back from Valentinos Studio.

one day you were sitting in your room doing whatever until the foor slammed open showing a very panicked Angel

"Motherfucker...YOU MADE A DEAL WITH THAT BASTARD!?"

oooh shit..he found out you made a deal with Valentino..and he looks more panicked then angry,but most definitely is angry.
