Agh, they got separated, but they're still quarantined from the rest of the fortress. Not sure if I should just go ahead and kill them or if I can use them to my advantage.
if dwarves, they wouldn't breed because chances are they aren't married. It's also very, very risky to use these werebeasts to simply bite dwarves to infect them, because they'd usually kill the dwarf, and if not they might be caught wrassling after the werebeast transforms back and start a loyalty cascade for attacking one-another in a non-tantrum-spiral setting.
Damn, they're not married. Still up for some creative ideas though.
