Somebody said when Stella moved in that she was wearing a wedding ring. If that is the case and she is married now then that could be the reason for not doing much this time around. On the wedding ring just going by what I read and guessing on the rest. Also it was possible when Gina moved in that they put her wherever there was an open bed at the time instead of moving people around. They may have wanted to keep Irma and Stella in the same apt. On this I am only guessing and throwing it out to think about.
I said that it was to fool the motion detectors to show they got more hits for more bonuses. I assumed that they would get more bonus money, do not know for sure one way or the other. Besides this post did not say anything about bonuses only to fool motion detectors.
They normally rotate up with the longest one there getting the big bed when one leaves. Nicole worked a deal to get it before when Danaya should have had it then.
