A decent chap. Doc's maniac smile and switch in atmosphere really gives off that there's more to him than meets the eye. Hopefully we'll get more backstory about him soon.
Furthermore...
What intrigues me is why the author intends to revive Shiho. Her revival is not really necessary to unfold the truth behind her death which both Sosul & Alex witnessed that day. Also with all the crimes 9AD commited and more to come, there's no way she'll have her happy ending with him without him atoning for his actions with at least death/prison.
Finally, totally not looking forward to next week's drama.
