They strung the tension through this episode really well, and I'm glad they dropped the truth bomb about Ainsley being the killer so soon in the season. I was afraid they'd drag it out.
Now we get to see how everyone copes and the fallout... which I was a little sad we didn't get from the start, but I get why they did it that way and I'm not mad.
But he srsly considered leaving his kid on the floor getting tased and potentially beaten to death for a moment for his own freedom so I do believe it now.
