Based on the picture. With her back to the window, if she lunged forward.....that's away from the window. So by the logic, if she lunged at Ava and end up going backwards, it would stand to reason that her momentum was stopped by someone or something and was redirected backwards toward the window. Lunging at someone with your back to the window but ending up tripping on something behind you and going through said window makes zero sense. And in one of the photos is right after Ava had her hand on Kristina and Kristina is falling back as she turns toward the window. Smoking gun, maybe not....but given her dumb lies and those photos it's not helpful to say the least.
