John Connor and Petros I give you blanket permission to read and talk about their minds. Both are normal humans without any magic powers, so neither would notice. Uhh PING ME? if I can be helpful about whatever one might find in their brains, or if you know their canons (Terminator 2 and Trinity Blood, respectively) you can totally reference those. have0wanderlust at gmail if I am not in chan, which is frequently the case.

Zim uh WELL! Unaired canon makes it clear that connecting to his brain drives that person CRAZY because Zim himself is just so defective. I have seen Firefly/Serenity, I know this is something River cannot control. I. MAYBE I SHOULDN'T JUMP RIVER WITHOUT COMMUNICATION!
