Brock has once again fallen back on a promise he made to Jake by missing a soccer game. Jake scored his first goal (okay, so it was on his own team) and Brock missed it. Feeling guilty because he's spending so much of his time helping with the baby and keeping his dental practice going, Brock promises Jake he'll finally build that tree house in the backyard they've been talking about. Reba warns Brock not to make another promise he can't keep. Brock shows up one day with a huge box containing all the parts to the tree house and promises he'll put it together. As Jake gets impatient waiting for his tree house, Reba decides to rope Van into helping her build it. They manage to put it together, if a bit lopsided. Brock promises to spend the first night in the tree house with Jake. While they're outside, Barbra Jean comes over in a panic because she can't get the baby to sleep. Reba ends up looking after little Henry when BJ falls asleep. Brock decides he can't have Reba clean up his messe (thetvdb.com)
