So many men are loyal to a fault. This is a bromance gone wrong.

-He invited Celestin to have sex with the accuser
-He lied to the accuser about Celestin's involvement until she lied about being pregnant.
-He publicly harassed the girl with Celestin.
-He wrote this film with Celestin.

I think he could've skirted a lot of this if he didn't still associate with Celestin, let alone write this film with him. I'd rather be a fair-weather friend than an accomplice to rape, personally.
