An older comment, I realize, but that's a relief! If that's still planned to happen, anyway. With how well written your characters are, when the time came, I'd be stuck trying to decide. Especially cause I don't want to hurt any of them!
Would legit be sat there for longer than I care to admit having an internal debate about it lol.
