Also, Liang Qi's stomach-churningly vicious beating of Maria.
Everything Liang-Qi does after Alphard abandons her, and at least a bit of what she does before that. Never before has a Psycho Lesbian taken the very concept of a Freak Out so far magnificently culminating in her death by Ua Virus, accidentally self inflicted. This shot◊ in particular. If you can't make it out through all the blood, she's smiling.
And in the last episode, Alphard SHOOTS HER OWN ARM OFF, and even worse, Canaan is left holding it. *shudder*
