I hope we get the chance to avenge Grace at some point as I was quite fond of her. There's already such a feeling of unease and paranoia throughout the game -- we can't trust anyone, we don't know anyone's true agenda, and we don't know who is actually out to get us or ruin us (maybe they all are). I think it'll take the game to an even higher level of intensity if as the MC we can also pursue our own agenda and plot against a couple of our supposed allies.
One concern I have is that the MC may be a bit too passive at times even though he's theoretically in charge of the team. He sometimes comes across as more of a consensus building corporate manager type than a commanding officer. It feels like any team member who feels really strongly about something can effectively set the agenda for the team. Elise seemed to make the raid on the warehouse happen (a decision I actually agreed with) while Safiya and Mireille (the two team members I trust the least) seemed to determine how much of the truth Vera would get to hear from the MC. I was hoping for a branch there where you could tell the madam everything as I'd like to have her on my side and possibly get someone else on board the vengeance for Grace train in case I can't do it all by myself. It could have been an opportunity to test the limits of Blume's ability to spy on us as well. I'm sure we'll need to find ways to communicate or do things outside of his/her watchful gaze at some point.
Here's my trust chart so far:
People I strongly trust: None
People I slightly trust: Lana, Blanche
People I slightly distrust: Elise, Dizzy, Vera, Hilde
People I strongly distrust: Mireille, Safiya, Aria, Blume (OK, possibly not a person)
Kill list: Safiya, Aria
This is a great game with a really unique atmosphere and psychological tension!
