[Eiji currently does not have a sense of taste, not that he's been particularly open about sharing that little fact. So he's been relying on how things look and smell just to gauge if it's safe to eat.

The bread looked and smelled good, so he took a few bites out of it before realizing Judai wasn't far away, looking disgusted after eating the exact same thing.

Eiji stares for a while, not exactly sure how he should react.]
