The significance of Molly's jumper

 (Sherlock meta by kathleenkellly)

I made a comment on this before but I wanted to elaborate. I think it’s very significant that they had Molly [in the ILY scene] wearing the jumper from The Empty Hearse.

“You thought he was the one though, the love of your life.”

Sherlock’s thank you to Molly was a day solving crimes together. One of the cases just happens to be a man catfishing his own step-daughter and Sherlock, well aware of Molly in the room, unleashes on him. He will not tolerate someone playing with another person’s heart and by doing so he shows Molly that he values her love.

Then that hallway scene. He brings up her engagement at last. It feels like it’s supposed to be a goodbye. He’s happy for her because she deserves love and she lays out all the reasons why she should be happy, but it doesn’t really feel like she is. They walk away with what feels like a lot of things left unsaid, because they can’t.

And then Molly breaks off the engagement. It’s not over.

Fast forward to The Final Problem, she’s had a bad day and wearing the jumper again. They finally say “I love you”. We’ve known it about Molly all along, but to hear Sherlock say it, especially that second time - it’s real. Whether you see it as friendship or something more, it was real then and it’s real now.
