I seem to have missed something. Buck task Daniel to feed BB wrong info so they can expose her but she does not post it. Daniel tells her that he knows she is working with the other side because he found something in he pocket and this implies he has know for days or weeks. Now my question is how dick Buck and Fisk know BB is a traitor? As far as they know she passed the test. Did Daniel tell them about the card he found while they were in his mother’s house? I am confused. How did they go from let’s test her to let’s kill her without any proof. Also how dumb is BB to not realise Daniel found that in her pocket?
