Makishima's work surely got easier with Sybil doing half of it for him. But since all the brains in jars are from aberrations, I guess it's not altogether strange they would behave so stupidly allowing Makishima an easy escape. He also managed to avenge Kagari's death on the side, which was a big bonus.

I was disappointed in Akane during this ep. She was totally passive and offered no insight or ideas, despite everything that happened.
