Just finished episode 9, the Cg cut-scene was amazing and the missions were fun, but let’s get to the point. During some of the mission Roland didn’t seem himself he was kind of condescending and seemed kind of jealous of the humans. I may be wrong but isn’t that a sign a rampancy? Maybe something happened to him during one of the attacks on the infinity or when Halsey “corrupted” Roland it fragmented him and messed with his neural network.
I think he is either bored, or Halsey screwed him up
