I liked Ianto. [She dodges, taking the chance he might be solid, and kicks out in hopes of making contact. Wouldn't be anything like a kill shot, but they could dodge each other for hours and she'll settle to kick things off (literally) with a bruise if she can.
She just has to be careful. Throwing force out without the expected impact can throw you off balance. She knows that all too well and uses it against her own attackers.]
