I think Cal had to deal with one of the most terrible cases in his life: having his daughter in danger of one day becoming a victim like the one on the case he was working on.
I understand his fear and his anger, but I wonder what would've happened had he not be a little blinded by the fact that it could've been his daughter the girl on the tape. I can't believe how some parents don't know the kind of children they have and act on whatever they tell them. Of course I know that as a parent you have to support your children, but you also have to know that sometimes they have to be responsible for their consequences.
I like how Gillian helped that poor woman and I'm sure her maternal instinct had a lot to do with it.
