Well, we don't really know how much retraining was needed. - I gave the options of having the CMO be either her, Pulaski (the sort of CMO Scotty would recognize!), or a new character, and CBS picked her.
and a first officer and chief engineer who speak proper english are much appreciated, no offence to those of you across the pond, but I'd begun to think the whole galaxy spoke American.
Ahhahahaha! Too bloody right!
