nah its to lighten the tone a bit. See also: the spat with that dickhead alien.
otherwise it'd be too grimdark. None of the characters have been drawn with the depth of BSG. They got away with a dark tone on BSG- nay more than got away, made it work really well because the characters seemed realer. They had time tos where they laughed, gambled and fought over petty bullshit.
so far at the mo you've got this starfleet vessel stuffed with wrong uns and ex cons, a captain who may as well be called Ahab. You need the light relief
