First I didn't believed that Jane is RJ, because I remembered that Jane was sleeping all day, all night while RJ was killing the last victim (5x22) but then I watch it again and I saw that Jane isn't always in a cam view and when the cam is back on Jane he was sleeping on the other side. I know that he could go to the toilet, but why show that he change his side. Or it is just a mistake of director.
