He blinked when his nose was tapped and looked back to Madoka's Dad, his nose wrinkled a bit in his best imitation of a frown. "It's not a theory... Only another Servamp can kill me. Or... destroying Madoka's gift to me." Maru hadn't admitted that part to anyone yet, not even Madoka. It made him uneasy to admit to such a weakness now. But it couldn't be helped.

What was confusing, was the way that Madoka's Dad held the straw out for him. Maru was hurting, but he wasn't so bad he didn't think he could suck on a straw. Not willing to argue though, he just went along with it. Arguing would have been tiresome. He opened his mouth to take the drink.
