Without live feed it's hard to be certain about anything - we see only what they (producers) are willing to show us and that's not much. One daily show covers about 2-3% of all the action of one day in that house, so you can imagine what we could be missing out. From the bits & pieces they are sharing with us, they are able to create a whole different persona for certain housemates (I'm not saying that they do such thing, but it's definitely possible).
