Princess isn't concerned. Any worry about her being more delicate are clearly not things that bother her in the least with the way she all but rockets around him like some hellspawned combination of cat and bird, noting when Thor's foot finally lifts in either an attempt to avoid getting tripped or to try and line up a kick for all she knew.

Not that she was giving him time for that! Nope, see that leg you're balancing on Thor? She's slamming into the side of it with a scraw, stubby wings flapping wildly in an attempt to throw him completely off his feet.
