Back in Season 8’s “The Prom Equivalency,” Sheldon and Amy exchange “I Love Yous” for the first time. Sheldon isn’t quite ready for the typical prom night tradition, but he does find himself ready for the next best thing.
Sheldon decides to finally tell Amy just how much she means to him. In a rare moment, Sheldon surprises Amy, but for all of the right reasons. This was very important for their unusual relationship.
Other honorable mentions include Season 9 where Amy and Sheldon get back together, which came after a breakup back in Season 8.
