I like to go against the flow, so I suggest we choose
E.
Obviously, we'd like to see how the raids unfolds. But do we have enough time to be a mere spectator and watch Cammies fighting Sabbat shovelheads for the whole night? A smarter course of action would be to use that precious time to get ahead of our enemies and try to understand better what's going on. Choosing E. would allow us to do just that by calling:
1. Humphrey Trentbridge, the Kine Home Secretary, in order to protect the Masquarade as the Prince ordered us to - it gets him off our back.
2. Antonia, our ghoul and secretary. We haven't used her so far, and we could ask her to compile all the available info we have on the Sheriff - we'd better know our new ally well in case she tries to betray us.
3. Oscar. Let's try to contact him and inform him that thanks to the video, we've got the Sheriif on our side and that he has no reason to fear for his life anymore (well, we think so anyway...
). If he goes into hiding for good, we will have lost a precious source of information, one thing we cannot afford to.
