Fischer isn't depicted as such. She's the violent kind of crazy, not the babbling slobbering loon kind. And the mind slowly eroding was more for dorf!Splint. I actually tried to make it seem like he's convinced Stova is haunting his hammer and talking to him (The voices he keeps referring to.)
Also, things that would be considered insanity among a rookie are entirely plausible and normal with Fischer, just because she's:
A. Armok's daughter
B. A relative of Chuck Norris
C. Just that badass
D. That special kind of violent yet stable crazy
or E. All of the above.
E: Ninja'd
Rose is basically relegated to alternating being drill sergeant for Splint and his two inept bodyguards and being generally nasty to people who annoy her gamewise. Plus it's pretty clear Mr Frog doesn't need protection (he's got a passing familiarity with firearms/mag-cel weapons, crossbows and chainsaw weapons, along with his night night dart guns hidden in his sleeves.)
Ah, you meant dorf!Splint. Yeah, I figured he was kind of losing it.
I think he was fine up until he got thrust back into overseership... that's probably what sent him sliding towards the edge.
And I agree... I don't think Mr Frog needs a bodyguard at all.
Come on, he blasts goblin-brains and DJs at the same time. What more could you ask for? And Mr Frog isn't in any immediate danger, unlike presidents and royalty. All three corporations (not including Stone INC) avoid killing him because he's basically their anchor in Spearbreakers. He's in possession of the only permanent miniportal in the fortress - if he goes, they don't have any quick way to get in and out. Splint's telepacks appear to only port directly into portal devices that have already been established, so they kind of need him there. I imagine that if he ever
was in immediate danger, he'd have an assortment of people (from multiple companies) porting in to protect him - probably without his knowledge. (All of whom would be armed with guns and high-tech weaponry... quite a bit better than a hammer, pitchblende or otherwise.)
As to Rose befriending Vanya... Vanya isn't the type to make friends that easily, unfortunately. Nor would she be likely to trust a female in the military.
All the same, I'm planning a sort of tour around the fortress for her in the near future, and if you want, we could possibly have them both have a brief (brief) conversation.
By the way... @Mitchewawa: Fischer wasn't drowning during your turn, and she didn't accidentally fall in. It was intentional - she was practicing breathing the water. Because she's that badass.
