She also has no soul

She sold her soul at the crossroads to get fingers... Gingers. Their soul-less-ness is inevitable.

But she could probably afford to get one.
She'd probably throw it away for not liking it, though.

Everyone but the PP Girls have fingers. Their hands are implied to be sticky on command (in the body swap episode).

Also, the Misfits.

She sippedt the truth tea.
