Penny rolls her eyes at the uttering of the threat but then she's off and running. 
Her skills as s Gymnast and her many escapes have honed her into a fine traceuse as nothing before her which is not living becomes not an obstacle but an apparatus for her to manipulate.
Her speed is no better than any of her team but her ability to flow over anything and keep going gives her a straighter line to follow.

Watching her move is like watching a monkey move through the trees, almost effortless and entertaining.
