[Wouldn't miss all the special~*~ food, so he will eventually unglue himself from Hima and go nom all the things. He realizes what Mokona's done, obviously, and even suspects who might be responsible for it. Although it wouldn't be odd if Kiseki itself had done it...
Either way, he won't question it, he'll just drink quietly (is there any point to saying he's being quiet? Quieter than even the usual), hoping it'll distract him from his thoughts on canon shenanigans]
