Sheldon becomes obsessed with the concept of mortality after a minor church event (a baptism goes slightly wrong). He applies his rigid, mathematical logic to faith and death, concluding that the probability of an afterlife is "insufficient." This leads to a hilarious yet touching debate with his mother, Mary, in the kitchen.
As the episode ends, the Cooper family is shown enjoying their desserts together, with Sheldon and Missy sharing a laugh about their earlier disagreement. young sheldon s02e03 480p hdrip
