It's a pretty solid suggestion, one that Oswald doesn't really have the will to protest against or offer any particular counters to. The highest priority task right now, it seems, is to make it through the rest of the pie without passing out right in the middle of it. He doesn't even think that his drowsiness is from any kind of additive because it just makes sense as a response.

He does watch Ed move, the way his stride is every bit as long and smooth as ever, which is both a relief and a curiosity which he doesn't have the focus to think about right now. He thinks he said something affirmative to Ed out loud, confirming that he's understood and will do his part, but it's honestly hard to be entirely sure so instead he just puts his depleted energy supply into eating, and then into draining the wine glass, and then taking both to the kitchen countertop which he briefly uses to brace himself against, palms against the edge, head swung down from the pull of gravity.

Upstairs feels a very long way away and he's not even really sure how long Ed has been gone, though he eventually pushes himself back to stand on his own (already wobbly) two feet and start to make his way up to the first floor again. He's not an especially subtle approach at the best of times, but even less so when he's on the edge between sleep and wakefulness.
