I am in a Social LS w/ Ariesol, I would never think he would do something like this, that being said...
Once Meghan hears about what happened I'm sure that she will force them to hand the Gem back. In no way am I defending Ariesol when I say this, but I've never seen him do anything Rude to anyone. Kinda wierd that something like this would happen. I do know how SE is though I don't doubt that it did indeed happen.
I'm really sorry to hear about this BS. If I see Arie, I'll ask him what happened, and ask why he didn't return Gem after it was requested,,,,
