As you probably remember, the Season 10 finale of The Big Bang Theory saw Sheldon finally present his Meemaw’s ring to Amy and propose to her in the the final seconds of the episode.
He asked Ramona to hold on, left the building, went to the airport and hopped on the next flight to New Jersey, only to knock on Amy’s door.
And, when she opened it, Sheldon was down on one knee asking the question I’m sure she thought she’d never hear.
After a full episode of everyone telling Sheldon that Ramona was actually hitting on him, he finally asked her what her intentions were, and when she made it clear that she was, in fact, totally after his nerdy body by kissing him full on the mouth, we saw Sheldon react immediately.
