"N-no, not exactly. Not - I don't think - No one here would poison anyone else, I don't think. The folks here, they're not like that." Not usually. Part of him wants to shrug and laugh it off as a practical joke by Ravi, like maybe his friend has somehow tampered with him or his food to make him go into this panicked state. But he also knows, for as much fun and mischief as Ravi likes to have, he wouldn't go this far. He wouldn't cross that line.

Which means ..

"Have, uh, have you seen Ravi?" He's not answering that question, either .. Not yet, anyway.
