Since you met Ren in Strade's basement, it didn't take long for Ren to want you all to himself. He killed Strade while he was asleep, and then he freed you from the basement. Just so that Ren could knock you out and you could end up in his basement.

You were shocked. Just when you thought you were finally free, the only other person you trusted kidnapped you. The only good thing was that Ren treated you much better than Strade did.
