This missing scene begins after the end of season 5, episode 7 - Death and the Maiden...
"How often am I going to see that look on your face?" Damon asked Elena as they walked.
They had left Stefan to bury Silas and were walking in the woods now. Damon had been quiet until now, and the question caught Elena off guard.
"What look?" she asked when he said no more.
"The look you had when he told you that he hoped you would be the one he saw when the safe opened."
She had been looking at Damon as he spoke, but had to look away now. "He said he was hoping it was both of us."
Damon snorted. "He did, after he saw that I was listening. But I heard him when he thought he was just talking to you. I know him, and I know what he meant. I know you, and I know what the expression you had on your face meant."
She glanced sideways at him as they walked, but didn't try to meet his eyes. "It meant I want him to be safe. You want that for him, too."
She saw that his face tightened a little, but he didn't respond.
Finally, she sighed. "You must think I'm pathetic. Trying so hard to save him, asking you to find him so we wouldn't lose him again." She glanced at him and let a breath out before continuing. "I still need you to help me with him."
"I'm a little more concerned about you being lured to a crazy witch when she..." Damon stopped and turned to Elena, "when she played on your feelings for him, when she made you jealous."
He turned and started walking again. "And when you keep telling him how much he means to you."
She had stopped walking when he did, and now hurried to catch up. "How much he means to us."
His face didn't change and he didn't respond, but she could tell he didn't believe her.
"They're all gone now Damon – both of the stupid witches and Amara. Jeremy and Bonnie are both back. Now all we have to do is make sure Stefan is OK, and things can get back to normal."
"Make sure he's OK," Damon said under his breath.
"Yeah," she said, finally grabbing his arm, pulling him so he would stop and looking into his eyes. "We both want him to be OK."
"Yes we do," he said, his face nearly blank again as he looked at the hand that held onto him arm. She took the hint and let him go, and he started walking again without saying anything else.
"What can I do, Damon?" she asked imploringly. "I just want him to be OK, then we can go back to the way we were last Summer."
They had reached the Boarding House, but had not entered. Damon turned to look at her, his face still fairly stern, and said "Just come back to me when it's done, when it's all over."
She grabbed both of his arms with her hands as she looked intently into his eyes. "I'm here, Damon. Here with you."
"I'm not sure it's over."
Elena cringed. "Damon, please."
His expression changed suddenly, he looked intently into her eyes. "Just tell me one thing, Elena. Just tell me that you told Stefan the truth."
He hesitated, and she thought of a number of things she had said to Stefan that he might be talking about. She almost asked what he meant when he spoke again.
"Just tell me you told him the truth when you said that you were happy all Summer. That you got the Summer of your dreams"
She smiled a little. "It's the truth, Damon. I've never been happier than when I was with you last Summer."
He leaned in to plant a brief kiss on her lips before turning to enter their home. "Then remember that. And remember how annoyed you were when he told you to give up on protecting Amara."
He turned back to her suddenly. She had been following him into the house and barely avoided running into him. "And quit thinking that Stefan knows you better than anyone. If it ever was true, it hasn't been true for a very long time."
"You're right", she said quietly to herself as he turned and headed for the stairs. "A very long time."
