I hated this twist. Doesn't she think? They have known for a long time that there was no physical evidence linking either of them to the crime. It was over until she decided that Colby needed to answer for his crime, without her Angelo has nothing.She also risked Dean, it is likely that the crime scene shows that two people were involved leaving Dean wide open to being charged. It doesn't make sense to me that Willow who has lived her entire life straddling the line between legal and illegal would be so black and white. Neither Dean nor Bella will forgive her ever. She sat there at their farewell dinner plotting to make him confess on tape and knowing that she and she alone was going to send her childhood friend to prison, leaving Bella an orphan. I know she already is but he was In loco parentis. If Colby had been in danger of being charged or had threatened to bring Dean down with him, then maybe but not in the,situation as it was.
