I think this is pretty much the sensical approach. She really is scary now, and prior examples of Thin Man work center on Mary which doesn't set a great precedent. On the other hand, she was right and never actually 'attacked' the Phalanx members. She just set up a trap if they decided to attack her. If they'd decided to discuss it, they'd all still be alive.
Hopefully for both Suspiria and Crest something positive can be at the end of this rather than sacrifice and one or both of them being the ever melancholy and unlucky in love symbols for the strip. I suspect there is a good bit to come though, and look forward to reading it.
