Irian doesn't really like being called a former spy but lbr she totally was one. I think their CR could be really interesting, especially since she knows what it's like to be on the other side of the coin and be an active part of an oppressive system of government. Part of her job, aside from designing more and better ways to kill people, was being assigned to military starships to watch their commanders and crews for any sign of potential disaffection with the Romulan Imperial government. She got a few people demoted or, in a couple cases, executed this way. At the time, of course, she believed she was doing the right thing. Loyalty! Duty! All that stuff. The Tal Shiar ran a great propaganda game. She saw through it eventually, which is part of how she got to where she is now, but yeah, suffice it to say she knows what it's like to be on both sides of the horrible totalitarian regime equation.

Anyway tl;dr yes let's do this thing.
