Personally, I think that Cinder's brains were scrambled by the outpouring of Ruby's magic (for the lack of a better word for her special power). She had enough wit left to fly out through the hole in the aerial Grimm that the outburst cauesd but she was too badly disoriented to think of attacking the unconscious Ruby. All she could think of was to escape; to get away from those impossible eyes.

She's probably recovered by now but it will be interesting to see if being at ground zero like that has had some permanent effects on her.
