When she challenges Dove to heal himself, something in him can't help but want to push back. Why wouldn't he be able to? He's fine, of course he can. It's not like he's helpless...

"...Of course I can heal myself... Here, I'll show you. Parvati..."

And he focuses-- or rather tries to. Unfortunately too much effort is being used to remain standing, and the spells he was already using took way more energy than they should have... Parvati does not appear behind him, and instead he's just standing there, sweating profusely.

He just did it. He just healed her, why can't he...?

So... he tries again. This time trying harder.

"...Diarama...!"

There's still no response from Parvati, and instead of being able to heal her, he just feels a rush of dizziness.

His legs wobble a bit before they finally cave in, and he lands on his knees. His head's spinning, and Parvati isn't appearing...

"...?"

He manages to look up at Hannei after a couple of seconds, feeling a little-- actually no, very frustrated.

"...This proves nothing..."

'This proves nothing'-- Dove, you're on the ground. Hannei's absolutely made her point.
