I had noticed Allelujah's split personality by the second episode. He'd already appeared to flip once from the first episode to the second. In the first episode he seemed like an unstable sadist, giggling soft and proclaiming "Hallelujah" upon him or Tieria scoring kills. In the second episode he seemed almost depressed about what the CB were doing and was very quiet. Same with the third and fourth episode. Now it seems he's flipped back to the version we saw in the first episode.
Also Wang still seems to have lost a lot of bust.
