1) Meg probably would in some sense - they'll probably just feel off to her and she wouldn't automatically assume ILLUSION but she'll know something weird is going on. Aerith might sense a strange aura about one of the duplicates but won't go poking at it or anything to see if it is one. She's not familiar with such things.
2) Meg might, if only because she is a demon. That doesn't mean he can't transmit thoughts/sensations to her, it just means she might catch on pretty quick. Not immediately, but quick enough. Aerith's magic is mostly focused around healing and buffing party members, so he would probably have no issue with transmitting - maybe something akin to magical static when he tries but it works anyway. If that makes sense.
3)I am all about shapeshifting, do ittt.
4)For Meg he could probably sense the fact the body she's in isn't hers - she's limited in her supernatural abilities atm so there isn't much to really sense about her. Aerith, though, has lots of magic type stuff flowing through her body so he can probably pick up on her healing abilities, the fact that she's half human and stuff like that.
5) I absolutely encourage any meaniebutt behavior to either girl. Especially Meg. She needs it :|
For Aerith & Meg
