Harley slid off his lap and onto her feet with what could only be described as clownish grace, since while there was no stumbling involved and it was all quite smooth, it was hard not to be clownish in a half-open onesie - and also she was Harley and thus always teetering right on the brink of being ridiculous, even when not actively engaging in it.

Anyway, once she was upright, she held out her hands for him.
