Okay before this gets to that point, the GM is going to insert a few points of 'reality' into the situation to allow both of your characters to consider what comes next.
1) Clem was wrong, her intentions are not in question, but in this situation she was taking advantage of two people, O'Connor and Darrell, and she got spanked for it. She can start to make it right with one of them right now, by agreeing to his terms, in a general sense.
2) O'Connor is/was wrong AND stupid, he absolutely should not have betrayed Darrell's trust OR risked Clem's life in there alone and/or without some warning to security measures. This method won't work to fix any of that so it is suicide, and there is nothing in his background that makes him suicidal, crazy yes, suicidal no.
3) Bookkeeping: Since I OBVIOUSLY had no idea this was going to go down this way, I glossed over Clem's recovery because I figured she would have plenty of time to rest up, since that is not the case, the first roll that needs to be made is her waking up recovery which I will handle:
8d6.hits(5)=5 She has a -1 CM modifier to deal with from here on that doesn't impact the rolls she has already made (I checked).
4) There are 7 other people in this confined space that have actions and/or input to add to this situation, so it will not escalate further without hearing from them, either IC or OOC. Clem and O'Connor can wait for that before acting further IC.
We now return you to your regularly scheduled Mexican Standoff.
