Randall was the first Pearson family member to notice Rebecca's memory problems. He takes her mild cognitive impairment diagnosis pretty hard and pressures her to do the clinical trial. Randall ends up having a major fight with Kevin over this and the two say hurtful things to each other. Randall says their dad died feeling ashamed of Kevin, while Kevin says the worst day of his life when Randall was brought home from the hospital. A flash forward into the future shows the brothers somewhat civil, but we'll have to see how this intense blowout pans out it in season five. Let's hope we finally get to hear Beth's take on everything that's happened, since she hasn't been too up front with her feelings about the whole situation.
