Stolen? Hardly! He'd been trying to look out for Lilia's health, and had... probably intended to give it back. Probably. It's not as though Malleus was just being difficult for the sake of it; he would never dream of such a thing. No little tantrums from him; he is no longer a child!

But the sudden shift in Lilia's expression makes him pause, and brings him back to the present. And then the softness of his voice, the genuine reluctance to let Malleus leave, makes his chest ache. No, he will never, ever leave Lilia alone, just as he wishes to not be left alone by Lilia. But this... this is different. This is something shameful that Malleus really must get in order, unless. Unless Lilia has completely forgotten about it?

It seems, perhaps, that he has. Then maybe if Lilia were to just agree to sit elsewhere, Malleus could pretend he is not in a state of duress, and stay. He opens his mouth to suggest as much, and the abruptly closes it again at Lilia's solution.

"...Excuse me?" Malleus is, of course, quite capable of biting. His teeth rival Lilia's own, but he hasn't bitten anyone in ages. "I do not want to bite you."

Malleus sounds truly baffled as to how that would solve any of the problems he's currently facing.
