I might have just precipitated an Andreas X Iota subplot by accident

Andreas isn't an idiot. He's pretty suspicious of Iota, but isn't about to start a fight with her when they could just as easily cooperate. (For one thing, he'd lose.)
I will, however, admit that "Antero Tolnay" is a bit of a crappy pseudonym.
EDIT: I've drawn up a Dark Heresy character sheet for Andreas (who, in Ascension terms, is a recently ascended Rank 9 Sage).
I'm not sure how I managed it, but his highest stat (after Intelligence, at 50 with Unnatural x2) is
Agility (at 52). He's completely useless in combat if you take his guns away, though (as expected), and he's had very little EXP invested in Forbidden Lore or extra wounds, but the way I set his talents up, he's more of a
Battle Butler or a
Jeeves than a Sage anyway.
The only reason he's not an Interrogator is because I wanted to spend his bonus Ascension EXP on Common Lore Mastery, which Interrogators don't get until something like Rank 12
