She'd sell you the shirt you're wearing right now, no problem, and you wouldn't even notice.Anyway, it would be nice if she would get a little more rounded of a personality than just "spoiled bully," though that seems rather unlikely as the writers themselves seem wholly unwilling to do anything of the sort (she is still more plot device than anything). But there are small glimmers here and there, like having the charisma (or general sway at least) to get ponies follow her along (Twilight Time); she has certain business savvyness (she did make the Foal Free paper a big seller like she said she would); and she does show cleverness and huge self-confidence that could be turned into major positive assets.Heck, why not have an episode of say DT and Apple Bloom, with a couple of other ponies, forced to work on a school project or something where they need to learn to get along with each other and not have it end with Tiara being the villain. It wouldn't even need to upset the status quo, but would take things somewhere at least a little different, and have the potential for a whole bunch of comedy in it.
