The episode that got me hooked was when they went to the premeir of Michael's rockdoc This Is It. Their reaction towards it was deep. They didn't really feel too comfortable but they were anxious at the same time. They felt it was too soon to see their brother preparing for the show that kept him away from them. But they banded together and went in.
They are also trying to record an album. There was an episode where they decided to go on lockdown away from everyone and focus on recording. They show them disagreeing with eachother but eventually things should come together in further episodes. But the brothers did stick by their brother Michael and continue to keep him in our hearts. As long as they do that I will support them.
