Mallory really just fumbled the ball at the last minute. Butcher was being an actually good father for a solid minute and then had to let all hell loose after her little mishap with Ryan.
I found it somewhat jarring to the point of it being funny how Butcher's beard just lost all white when Kessler took over. I get the intention behind it, but I'm just imagining Butcher stopping for some makeup for some Extra™ Beard Spray.
Also, damn you writers for jumping straight for the gut with Kimiko's first words being those of denial, anger and loss. Not cool.
