This takes place after Elliot finds out the truth behind his wife's death and goes to Olivia to recreate his bond with her... (probably a one-shot but we'll see)

This time when she grabs his hand and she starts walking, she doesn't let go.

...Elliot untangles her left hand from his which he had griped tightly moments ago and puts it on his right shoulder without breaking away, and holds her closer. "You're killing that dress" He says smoothly... EO slow dance at the wedding (Elliot Stabler, Olivia Benson)

Based on the Organized Crime episode "The Stuff That Dreams Are Made Of" What if Olivia actually answered that last phone call? Rating for language.

"It was the one thing he'd always been certain of. The one thing that kept him going even when he was drowning, his love for her. At that moment, his focus was on no one but her. He locked eyes with her and said the only thing he could think of, the truth." My spin on last week's episode: The Stuff Dreams Are Made Of. EO
