"ah, don't do that!--I wouldn't have guessed it, but during that whole thing with the spell-- well, you know, Feuilly and Bahorel switched, and Bahorel says apparently it's so, and well--" Joly laughs again. "--Bahorel would know! He's his own sort of expert in that."

And Feuilly's not, which is probably why he'd fail to recognize how serious some injuries can be.
