Watch on Philo! - Philo.tv/DTH Baby Jack is back and better than ever, out there throwing the baseball with Nathan. It's almost as if the ordeal of diabetes is behind them—her words, not mine. Graduation is quickly approaching for the first time in 12 seasons. Nathan and Elizabeth are as in love as ever, matching outfits and all. Rosemary is talking to Bill about how she isn't going to publish this story without knowing where the gold is. She suggests interviewing Edie—maybe she'll open up more about what she knows. Nathan is talking to Oliver and gives him a form stating that he'll be stationed in Fort McNeil after he graduates. Oliver doesn't seem thrilled. Rosemary goes to talk to Edie and notices a map behind her. Edie tells Rosemary that her uncle drew it. Silly uncle, always drawing maps. The kids all present their project-based learning projects in front of parents, and Lucas is impressed. He tells Elizabeth he's going to talk to the district about implementing this at other schools. Elizabeth gets a letter from her grandma, telling her that Cape Fullerton has great doctors and essentially encouraging her to move for the sake of Baby Jack. But Baby Jack is fine. I'm sure there's nothing to worry about. Lucas and Edie are playing cards, talking about her uncle, and they decide that maybe they should try to find the gold coins and return them to their owners. Bill, Rosemary, and Nathan are looking at the map when they suddenly notice that the well is GIANT on it. Maybe it's a clue. Maybe this map is actually a treasure map! Oliver fails his final exam on purpose because he doesn't want to leave Hope Valley. Elizabeth goes to talk to him, and then they play tag. Edie and Lucas decide to go dig at the well when Rosemary, Nathan, and Bill show up too. They all start digging together and find a chest full of coins! They go back to the office to discuss. When Edie realizes the map is a treasure map, she figures there might be a secret message from her uncle. She holds it up to a candle, and a message appears. He explains how he found the gold and used it to pay for Edie's law school. He says the rest of the gold is hers too. There's a sweet storyline about the townsfolk rallying around Angela and Minnie, which is nice. It's graduation, and since it's being held at the saloon, there's a dance afterward. Lucas tells Elizabeth that the school board is interested in hearing more about the curriculum, but she's not sure about leaving Baby Jack right now. The season looks to be ending peacefully until late that night when Elizabeth notices Baby Jack lying motionless on the couch. She screams for help. Faith rushes over and says, "We got a bad batch." She tells Elizabeth that maybe Cape Fullerton would be best for Baby Jack after all. So they hop in a car, and she gives Rosemary a note to give to Nathan. Nathan and Allie go after them, honking the horn. They all get in the car, and Nathan tells Elizabeth that wherever she goes, he goes—and then they kiss.
