Spear guy died once already and got brought back accepting a dark power. His eyes are just weeping wounds, but he still can see. I don't have a choice but to let him die if it is the fate of the dice, it's the others I'm more focused on.
They can escape on the raft into the lake nearby and that would push story events along... so I could let them escape into this lake where they see a fisherman dump a squirming burlap sack into the lake.
The only issue is that they are recently strong enough to remove lycanthropy on its own. It would definitely work for one or two of them, I could have them change that night and retreat to the Castle of Strahd to report in. Putting them in the castle gives me several advantages and probably separates them from the source of the cite for a while.
I think I have a good path forward to let them escape infected and possibly just have one death. It's still a while to the next session but it will likely be a big turning point after they have had a few big wins in a row.
