My idea for the Shamy Reconcile / Proposal
Penny goes round to confront Amy. And shows her PART of that film.. nothing abut the ring. Penny Tell's Amy she needs to confront Sheldon about his feelings before throwing him away as she thinks Amy is making a huge mistake. Amy goes over to confront Sheldon in his apartment. And just asks him to be honest about his feelings. He has his pride as per Sheldon attitude but then Amy tells him she has seen the film of him practically breaking down so be honest with her.
He breaks and is eventually honest with her admitting she is on his mind all the time and always has been. That night he messed things up. He was nervous due to what he had planned so was thinking of things to distract him and stop him becoming to nervous. Amy explains that she didn't feel like he loved her, At this point she is becoming more understanding. Then Sheldon says he ruined it and she walked out and stopped loving him.
Amy explains that she never stopped loving him. At this point they start becoming very soft with each other. Sheldon says he would like to continue with his plans to prove to her how much he loves her and wants to be with her, If she has no objection to it of course. Amy accepts. And with that he sits her down in his spot, tells her to close her eyes as he has a surprise for her. Retrieves the ring. Kneels down in front of her with the ring out. He tells her to open her eyes and when she does, she is stunned..
"Amy Farrah Fowler, I know I haven't been the best boyfriend, And I apologise. Would you do me the honour of becoming my wife?"
And then a snarky comment about how he will be better then Leonard and lets show them up. And with that, he puts the ring on her finger, they stare at one another smiling and then kiss
