Okay, I was wondering about this kinda, sorta. Somewhere in the movie I got a bit confused, because after Joe rescues her, we see that Pryce is watching her too. And then it looked like Maria was in the know, like she knew that Pryce was watching, and she was simply a part of his plan, but she didn't know that Joe was her father. So then the big reveal at the end left thinking okay, so she didn't know Joe was her dad, but at some point fell in love with him, in the process of helping Pryce?
I guess that "knowing look" she gave the camera in her home threw me off a bit. So I'm really asking was she helping Pryce, not knowing that she was helping him get revenge on her father?
No two persons ever watch the same movie.
If she had the tendency to "take home stray puppies", why didn't she already have "project" by the time Joe came along?
