I'm pretty sure they all are talking about these "theories" and "conspiracies" each day, simply because they are bored and need something to keep their mind busy with. They probably come up with ridiculous plots all the time (especially just before and after nominations/evictions) and most of them are total rubbish. Just because we don't see them disscusing these things on each highlights show doesn't mean they don't do it. We are mostly shown only those times when someone is close to or hits the mark and that's always gonna happen if you talk long enough.
