Dante will be hunting at the beginning of the event, and offer food to those who cannot obtain it for themselves. He'll be hunting out particularly troublesome infected (Loki primarily) but won't be making a point to kill anyone that isn't proven a threat.

He will, however, go after Loki, and upon defeating him will then gain his infection. Dante will be getting the Star infection, so at that time will then decide to spread it himself. Yay 8D. Loki is the best mentor.

I believe Alastor and Lily were going to help bring him down/cure him after that point?

Am I missing anything?
