Sounds like a hectic day. -hugs- And, I dunno in the RP. If you want Remi to start destroying things, he can lol. One of Kiyo's characters might know what he is, I can't keep up with which characters know what about Remi lol. I know for a fact that Ambroise knows more about Alpha Stigmas than even Remi knows, but being a familiar to a wizard it's not surprising he has some knowledge about things. It's up to you really how you want things to happen. I don't really care either way.
The only way to stop Remi is to have someone close his eyes for him. Once the alpha stigma awakens, Remi is powerless to stop himself. It's like watching what's going on from inside his own body but unable to control any of it.
I've never been sprayed with a fire extinguisher, but I can imagine it wasn't fun.
