“A Swedish Science Thing and the Search for Daniel” isn’t the flashiest episode of Young Sheldon , but it might be one of the most well-rounded. It’s funny, it’s warm, and it delivers the show’s core message: genius is great, but family is the real prize.

While Sheldon spirals, the B-plot belongs to the unsung heroes of the Cooper household: Georgie (Montana Jordan) and Missy (Raegan Revord). They’re tasked with watching the school’s pet snake, Daniel, over the weekend. Of course, the snake escapes.

★★★★☆ (4/5)
