Who else hates FBI agent Dennis Abbot? (or whatever his name is)
As far as I'm concerned I think this character is completely irrelevant, came out of nowhere, he hasn't brought anything interesting to the series, he's just some random guy that you could think is there just to annoy people. He has no background, we don't know what he's fucking doing around here, to me he had nothing to do with RJ saga's ending. Also I would expect his shoulder to be checked when he showed up at the CBI to close it down.
When you have excellent characters with an interesting background and a developed story like JJ LaRoche, Kristina Frye, or even Agent Darcy (who screwed up the operation to catch RJ in season 4 finale), I think it is shitty writing to create characters like Abbot. He's useless. He has nothing to do there. He's a mistake.
Crappy Red John by the way.
