She has shimmer speed now whenever she needs it. Everytime she uses it it leaves a pink streak of light from her eyes. You can see it before the explosion streaking off to the side of the hexgate chamber.

She realizes the hexgates had a cooling / ventilation shaft, which she zooms in on and smirks as she realizes Jinx used that vent to escape.
