Shae...I really didn't like for some reason. I think the actress just clashes far too much with what's in my head (which, admittedly, is probably less-than-accurate).
I agree, she's very good and is being set up to be an interesting character, but shes very much not Shae, who doesn't seem to have that much depth in the books.
Raxtel would like to quick-draw his grapnel and line gun and try to reel in Sarge like some particularly authoritive fish before we lose him in the middle of the rebel infested, colder-than-space tundra.
