Maybe… Two or three episodes previous, when Mal and Co. got the contract to smuggle cattle to the frontier, there was a scene where she confronted some petty mid-level criminal and seemed to be able to read his mind and throw his own past back in his face, despite having never met the guy before. She also seems to be able to sense when the “blue hands” people are nearby, and arguably had an episode of precognition when she attack Jayne shortly before he tried to sell them out to the Alliance. At this point, it seems clear that she has some form of psychic powers, which were almost certainly the reason for the experiments conducted on her by the government. Wether these powers are purely the result of those experiments, or enhanced her native abilities remains to be seen.
I wonder if Kaylee is wigged out by River’s apparent psychic powers, her cold-bloodedness in killing three men, or just shame that River stepped up and saved the day when Kaylee chickened out. Near as I can tell, only River knows that she panicked…
Yet again, this was the best episode yet. I think I’ve said that in every Firefly thread to date…
