For the fourth wall breaking bit, it's to establish where she is at the start of the RP.  And as for the trading aspect, shoot, I didn't expect that to clash with her personality.  We could probably say while she's good at trading, she's not the best at communicating during it and prefers to do it in private, even though in her head it was going to go well?  Again, didn't realize the personality clashed with the character gimmick.  As for her backstory, I'll try to shed more light on that.  I'll fix everything once I'm able to be on my computer.
