[@Pirouette] True, Sebastian does deserve to die. On a side note, how will Ann be able to cope with her part in a larger portion of the deaths that happened. Sebastian was giving everyone else a choice until Adriane came in with her Semi and doused everyone in acid, not to mention how she killed 7 people directly when you count the hostages in the blood clot-thing. Will that way on Ann's conscience in anyway, and does Adriane even have a conscience for that matter, cause it doesn't seem like it to me.

Ariadne doesn't care and it is part of Ann's character to charge in rashly. She holds the twin's strength and power while Ann would feel guilty as she is the twin's conscience and intelligence. Then again, it is a situation that can be easily consoled. Ann would later see the situation for what it was. Sebastian chose to hold people hostage and kill many more before that. Sebastian's power was the one that killed people, not Ariadne's. Aya had the ability to disable Sebastian earlier but did not do so. 

Yea, that's pretty much it.
