I would never set the Enginseer on fire!  Electrocution seems like it would be much more effective.<br/><br/>Yeah, I don't actually see her having a role on the ship (Master of Arms or Master of Ordnance would be closest, but even they don't really fit as I doubt many humans would follow her and she is lacking some skills).  I could see her maybe commanding a small team of the less xenophobic crew, but that is about it.<br/><br/>I guess maybe Twistcatcher (though she is still lacking skills), though she'd be more likely to try and enlist them into service than kill them... ooo.  Could she be Twistcatcher and lead a team of mutants she has recruited?
