Just speculation:
The lady in the photo could be Red's wife, which could make him a son-in-law of Berlin.
Berlin seeks revenge on Red, perhaps mistook that he was her daughter's killer.
Very likely Red is Lizzy's father with that mass burn mark, as Red didn't mention to her he was the one who saved her from the fire. Red hid this to hide the truth. Red said he never lied to Lizzy. This is the only thing that he had to lie to protect her. —Preceding unsigned comment added by 210.195.81.227 (talk • contribs)
