Well, as I am about to post, Stukov will accompany her should she decide to go for warp travel anyways. He just tends to advocate not using warp powers. He has been along for her other shenanigans already, and Ben sure won't be doing it, eh? (Well, post if I can get it posted fast enough before a two hour watch, but it will be up tonight!) 

Consider the armsman feeling a pang of guilt for not letting her prove herself reliable after the mishaps. He doesn't dislike the psyker, he does not trust the powers.
