So the way it was explained in the link I provided was that it had something to do with the scene where Isaac walks in the room and says "Electrified the windows?" and Allison confirms such. Although its a stretch, in the way that the bat being electrified jumpstarted the Nogitsune in Stiles, the person suggested that Allison's may have been jumpstarted as well by maybe being too close to the window, etc.

Stretch, but that's what they thought of lol
