Uh...Is that Strephon, with his mortal and fairy halves coming apart?
No; it's just a random person who's been stabbed and trapped in the Sentry box for the entire 2nd Act.
I recognize everyone on stage! Well, I am not sure about the random person who was stabbed but I think it is a savoynetter.
It's probably best you don't know. :)
I have to admit to hoping this *didn't* happen.
I never realised Private Willis had such a vicious streak.
