What do you think is going on?

How long were you in the building while it smelled of gas? It's possible that the gas affected her cognitive abilities (it does that).

I was gassed once in college and went to a language table for dinner right afterwards. I was pretty good at this language, but literally could not put three words together correctly that evening. I think I went to bed right after dinner and slept all night.

I wasn't aware of how I'd been affected until the next day.
