I think I'll go with pilot #2 for my vote--if it's preferred that moments of characterization also move the plot along, the "ghosts" give us a chance to briefly address the crew's beliefs. I'd also be interested to see if LT Cortez jumps straight to a supernatural explanation or if he is someone who is religious but looks for natural causes first.<br/><br/>I don't have any strong preference for the nurse's qualities. Marah is self-aware enough that she'd prefer someone warm and friendly to put her patients at ease--she knows her directness and slightly reserved manner are not ideal for a doctor of a predominantly human crew.<br/><br/>Unrelated, but one thing I wanted to mention about Marah is that if's she not busy with her duties she's definitely going to try to be on the bridge when the ship arrives at an unexplored system or she learns they are approaching a strange phenomenon--not surprisingly this kind of stuff is the reason she prefers practicing medicine on a starship. (I also just like the idea of her hovering around next to the captain's chair like McCoy often did, heh.)
