Thanks.

[Li-Na repositions herself a little so her legs don't look like they're just flopping everywhere]

I remembered her legs giving out. She somehow survived her fight with Eshi and somehow got back to the ship. I don't know how. She'd done something that should have killed her, but she survived. Only, there were side effects. She could barely move her legs, there was a weird pattern on them, and her Innocence stopped working.
