i could see her making him take some and sort of being like: whoever gets it in the mouth first, do the thing. SHE'S NOT EXACTLY GOING TO BE THINKING SAFE FOR HERSELF SOB but she will want to make sure the thing gets drugged. she'll def be aware that bart is the faster one here, though, and probably tell him to be ready for a quick escape if necessary.

and no worries over the costume/identity! he might get an eyeroll from annabeth if only bc sigh these superheroes on the turtle and their secret identities.
