My understanding is that she got into a scuffle or two at Estrella. Wasn't she removed from a double cell and placed in a single after a physical confrontation with a roommate? I don't have a link for that but if anyone else heard such a report and can remember where, please speak up.
If the report is true it means not all the other Estrella inmates liked her. And some (at least one but I bet more than one) of those who did changed their tune.
Plus, according to Sandy Arias, Jodi likes her privacy, so it may have been a calculated effort (surprise!) on JA's part in order to get "private accommodations."
Makes me hope she does get to the "dorm housing" level of custody. It will make her nuts to have to put up with other people, most of whom she will undoubtedly feel soooo superior to.
