For Tales From the Borderlands players, what do you think of Vaughn and Yvette?

Personally, I dislike them. They were alright in the beginning, they seemed like nice characters. But both decide to take Vasquez's deal and betray Rhys. Vaughn may have apologised but he still took the deal, Yvette didn't even seem like she was sorry. Bad mouthing Rhys when he was disguised as Vasquez not once, but twice. Quite vehemently as well, it's hard to believe it was an act to get herself ahead in the company whilst still having your back.

Given both of their betrayals, do you still like them as characters or do they seem rather distasteful after choosing to betray Rhys? My friends still like them, but I just can't get on the band wagon with them for those two...
