i haven't seen anything about this yet, so hopefully this is an Original Thought™️
if we are going the mutated-simon route here, i like to think that he also picked up more than physical mutations. HEAR ME OUT:
simon is able to communicate telepathically.
LIKE!!!!!! ellie was able to communicate with simon! why would it be out of the realm of possibilities for him to ALSO be able to do this?
imagine (if you will) grace going about his business, thinking thoughts and so on, and simon. responds. didn't even register that grace hadn't said anything (in simon's defense, he's so used to him yapping), which leads grace into a whole new rabbit hole of trying to figure out what is UP with this mutation.
and, of course, hilarity ensues: simon tries to turn his telepathy off, grace cannot keep his gay thoughts at bay, y'all know the drill lmao
also idk if simon should be able to hear rocky or any of the eridians or not, just kinda depends on what you think will suit the situation better!
