No luck with Mr. Sargeant. It turns out that all his motives are frozen, and his favorite food is still O-Positive. Resetting him didn't help either.
In his bio, it says that Bobby Sargeant is your worst nightmare.
If only they knew.EDIT: It turns out that his hunger motive isn't frozen, and neither are his other ones now. Eating normal food doesn't fulfill his hunger, and he has the vampiric vigor moodlet. He's also not aging on his in spite of it being his birthday.
I hate you, Mr. Sargeant.
EDIT 2: I moved them to the clipboard and then back again. Still no luck for Bobby, but with the added "benefit" of everyone's 20,000 point wishes to be worth over 1 million being dropped. I have one last solution, which would be to give him a Bottled Witch's Brew and see if becoming a witch will help Bobby.
EDIT 3: Turns out that Bobby is still a vampire. He reverted back to the vampire skin. The Witch's Brew didn't work on him (and the Graves ended up spending upwards of 50,000 buying out the elixir shop until one popped up). I tried another potent cure elixir with no luck. If this means failure, hey, at least I got one immortal down and it wasn't Journeyman's meanness that brought him down this time.
There isn't any option for him to get a cure at the science lab either.
