One Tree Hill
Jacob and Rachel attend OSU shortly before they got engaged and married. When Jacob got a football scholarship he wasn't sure if he was going because he didn't want to leave his sister or friends behind though Brooke encouraged him to go and play football and also told him he should take Rachel with him because Brooke knows Jacob loves Rachel. Later down the road Rachel actually applied for Ohio State and told Jacob which made him happy and told her about the football scholarship and he wasn't sure if he was going to take it until Rachel applied for the same college. When they were about to leave for college Jacob and Rachel had a going away party and saw a teary-eyed Brooke and made it Brooke sad because she had protected her brother for so long and she loves him dearly.
