Eh. There's both a Wych and Solitaire on the ship, it's not as though a space marine can lord around the crew, immune to death, risk and consequence. The XO can always try to play shipboard politics and try to cultivate the goodwill of either.<br/><br/>Granted that any of sort of thing depends on if either would bother to listen if told to do anything. Eldar are all peculiar and such.
