Guess he figures that by now, tis pointless. His focus is on "fixing" this whole mess, and taking Stefan down. His sister & Kate are both being blackmailed by Stefan into doing unethical things.
What is interesting to me is that Roman used to be a "by the book" cop, a direct opposite of brother Bo. But now that he is no longer on the force, he looks the other way, keeps some dirty deeds under wraps, is willing to bend the rules, etc. I don't mind, cuz otherwise every single person in Salem would be behind bars, and that would not be any fun. No more Horton square, cop shop interrogation room, Pub, K mansion, etc. etc. LOLOL
