Mhalir could argue more but he's pretty sure at this point that it's futile.
- he has to get control, even if just for a second, he needs to convey to Leareth that something is wrong - just long enough for Leareth to be suspicious, wonder what's going on, remove the Thoughtsensing amulet...
Mhalir tries, desperately, to wrestle for control of the Andalite body - he can't - anything, if he can just make him walk wrong, Leareth will notice that, he knows normal Andalite body language - just make him twitch somehow - but he can't –
He's going to die. He's going to die and Leareth is going to keep his word, and take the side that didn't backstab the people who surrendered to them, and - it won't all be for nothing, the surrender, what he's given up on behalf of all his people, for a chance at a better, less pointlessly stupidly wasteful ending to this - but it won't be a quick clean victory, there'll be so much bloodshed, he HATES it -
Somehow the part that hurts the most, the sharpest grief in that moment, is for Leareth's friendship with Matirin. Leareth, who has so few friends, so few people he trusts at all, much less people he considers his equal; he's been in Leareth's head, he knows the warmth and closeness he feels toward Matirin, suspects it's more loadbearing right now than even Leareth realizes, and he's going to lose that in the worst possible way...
(He's confused, something doesn't add up, but the confusion is a faint background note behind the rising panic–)
- scaredscaredscaredscaredscared -
Mhalir flails for control for long, pointless seconds, but Leareth's magic - that was supposed to build trust, to make it possible to be allies, it's so maddeningly ironic - holds him as surely as steel chains.
He settles for screaming at the Andalite in thought, not even words, just as loud a distraction as he can manage, maybe if he can get him to stumble, or just seem off if Leareth speaks to him...
