Why didn't Harry tell Bishop he had nothing to do with Cape Town?
SPOILERS
Dean manipulates Bishop with lies about Harry and the operatives in South Africa were taken out by their own team member. Dean paid him a lot of money.
So when Arthur Bishop brilliantly gets Harry to bypass his own security and gets him out in the parking lot helpless in his wheelchair he asks Harry "Why?".
All Harry had to do was deny his involvement in the killings of the operatives.
But he didn't. He shrugs and says "Cape Town." He seemed resigned to his fate.
He was Bishop's mentor. Why didn't he deny his involvement?
Possibly Dean paid Harry the "20 million" to turn a blind eye on the treachery? That is the only scenario I can see that would not make that scene a plot hole.
Correct? Or was it a plot hole?
