In Season 2, episode 3 - "Hunting":
Logan humiliates Greg, Tom, and Karl with the "Boar on the Floor" game; Roman takes out his phone and tries to record.
Perhaps it was really Karl who taped Roman's breakdown at the funeral (and not Ray, who is also briefly humiliated in this episode)?
If so, it would be payback.
