I'm a little unsure of what Mikael's best role in this might be.
With the wall and door between us, I can't see him getting a chance to distract her with a charm roll first before Sabine is on her.
Stina has Tinker down.
That leaves his other high-ish skills as Contact, Investigate, Comprehend, and Empathize.
Mikael could go in before Sabine and attempt to talk her into unhooking the kids to bring them out safely. Or come in after Sabine and do the same while she has him at gunpoint.
What do you think, Rage?
