Charles tells Cassie that he plans on joining the army to help pay for college, and she begs him not to, even though she knows they aren’t together. She struggles knowing that she can’t live without him and hates being broken up. Sage pushes her to take a stand, and she decides to propose to Charles, who accepts immediately. The two implore Eddie and Jenn for their blessing, but Jenn talks them out of it by asking them to wait. Secretly, Cassie and Charles continue with their plans with only Lizzie knowing about it. Lizzie continues to have problems with the school musical when it’s cancelled in hopes of stopping a possible riot when people see inter-racial couple Lizzie and Andrew together in the show and in real life. She decides to stand up to the school and urges the cast to walk out until the censorship is lifted. They end up performing in detention to an amazing reaction, proving the musical can work and getting it back on schedule. With the help of Minnie’s diary that Lizzie found in the attic (Season 3), Eddie and Cyd continue to try solving the mystery of the money. They trace it back to Crawford, who Hazel tells them knew the Glass family back when Minnie died. When approached, he tells them that it was actually the Commissioner who paid off the Glass family as hush money so he wasn’t blamed for setting the fire. Eddie gives the money to its rightful owner – Cyd – after the mystery is solved in her family’s favor. Tay tries to help Nat Ray through his issues now that he’s been turned away by the veteran’s hospital for treatment. He writes a song which gets tons of press, including being recognized by the White House after Jenn sends a letter. Lizzie finally breaks down and tells the family about Cassie’s secret pending marriage, and the family rushes to the courthouse to be there for Cassie. They get there as Cassie & Charles are exiting, but find out they didn’t go through with the marriage. Back at home, the mother’s group worked together to organize a quick “reception” where Charles and Cassie decide they still want to exchange their vows that they wrote in front of their friends and family. Before going bed that night, Eddie finds a letter from Cyd that includes a check for half of the money. Their kids are all accounted for, and they are about to get out of their debt – not a bad day for the Sutton family.
