Warrick's supposed to be there, trying to comfort her /hug her after her accident (supposed to be in Built To Kill part2). You can offer help and support even if you are married. I'd rather see Warrick tryin to help Cath out even if he's married instead of not doing anything. He's married, he's not dead as we've said a couple of times and I kinda think it'd look stupid of him to run filing for divorce before he'd try to hug her... That's not unfair imo... that just shows he does care, which is why are are here I believe.
