I don't know if it was bad writing but it felt odd how quick Oliver became convinced that one of his team would turn on him. I felt that Ollie would have had at least a moment of doubt and at least talk to the team before spying on them. It also was odd how Rene made the deal with the FBI about his daughter and not tell Oliver earlier when it was Oliver who got Rene a second chance at a hearing to gain custody of his daughter.

And Diggle seemed a little too surprised when Dinah said talked about Vigilante being her old boyfriend. Didn't she tell already tell Diggle about that?
