Several things... Heidi is already out of the hospital (she wasn't even in that long). She was NOT hospitalized for their seclusion in the hut. Heidi got ill after a challenge that was filmed on Saturday. Spidi were only secluded in the hut for a couple of hours (not days) so there would be footage of them in the room that could be shown. The cast voted for them not to be allowed to return, but the network made the final decision of course. During the time Spidi was secluded in the hut they were 'plotting and planning' their next way to get time out of the jungle (having already spent more time at the local resort nearby than in the jungle). They didn't even seem to realize that they were being recorded because they were being horribly foul about the cast, crew and network. The only reason they returned in the first place is because they were informed they would be in breach of contract for quitting the show without being voted out. The cast has been upset about Spidi being allowed to return because they were told (on air) that it was their choice, yet even though they decided against their return the producers allowed their return (controversy creates ratings). Several cast members said they plan to reveal the whole truth after the show ends.
