- "I just felt trapped. By this town, by this family. Everything was getting so bad, and I just never saw myself escaping. It's like the only future that I saw for myself was a life that I didn't want."

Return of the Kent family
When Martha Kent died, Sarah went to the funeral with her family. There, she met Jonathan and Jordan Kent again. Sarah said she was sorry for they loss. When her parents left, they talked about the summer they met. Then Sarah asked what had in the Kent farm barn, so the twins accompanied her there. While in the barn, Sarah said that almost anything there could kill them and that Smallville sucks.
Sarah then asks for a phone number from one of them, Jonathan thinks it's his but actually Jordan's. She then picks up the phone and says that there will be a bonfire tomorrow and he can go. Jordan tries to impress Sarah by climbing on the scaffold without a ladder to reach the router, but he falls hard on the ground when the straps that hold the steel beams are broken. Jonathan then tries to save his brother from the steel beams by jumping in front of him. So Sarah runs off and tells Clark.
At night, Sarah goes on a bonfire with her boyfriend. There, she meets Jordan. She told him about her own mental health struggles. While they talk, Jordan's attraction to her becomes overwhelming and he kisses her passionately. Sarah reveals that she has a boyfriend, just as he appears to fight. She tries to stop the fight but Sean's friends show up and beat Jordan and his brother. Then suddenly the fire explodes. So Sarah's father is called to put out the fire. The next morning, Sarah goes to the Kent farm to see how the twins are doing. They talk about what happened the night before and later she gets in the car and leaves.
