I find your logic impeccable.Going through the vents is likely to blow Kana up.
Sending someone to stop Agnieszka is likely to blow whatever poor soul we send up.
[X] Keep following them, but don't try too hard to stop them from leaving
Plus, this one will get our boss mad at us, which means it is the most Kana choice available.
It's Kana, outpacing and stopping a newtype while injured is exactly what they expect. It would be a perfectly reasonable outcome if it would actually annoy our chain-of-command for us to do so. Honestly, if they actually wanted her stopped then they should have demanded that we not cause a diplomatic incident by confronting her. If they had, then we would have been through those maintenance shafts and sitting in her cockpit before they could say "Please, no. Not again...".We're officially walking wounded, so they can't get too mad at us for being left behind. Right?
