This missing scene continues the scene between Damon and Elena near the end of Season 4, Episode 3 – The Rager…
It was taking longer than she would like, but Elena was finally gaining control of herself. Damon didn't back away from her, didn't even stop stroking her hair - but she didn't mind that. It helped her finally quit thinking about what she had done to Matt. One of her greatest fears - that she would come to her senses next to Matt (or Jeremy, or Bonnie), who would be dead because of her – had almost come true. A fear that would have come true, if not for Damon.
As soon as she was sure she could speak reasonably calmly, she said "Thanks for stopping me, Damon."
He pulled his hand back, but stayed in place and kept her eyes. "What can I say? I've got Matt's back."
Elena shook her head. "What are you talking about? I had to knock you away from him just a few days ago, and you said you would have killed him."
Damon glared. "And you almost did kill him, Elena."
Elena grimaced and looked down, before Damon's words lifted her eyes to his again.
"Between you and me, we've got the quarterback covered. Let's just get you taken care of."
Elena nodded again, "Okay."
"Are you still hungry?" Damon asked softly, though his face was still serious.
Elena shook her head. "No. Not right now." Then her desperation returned briefly as she added, "I took too much…"
Damon put a finger to her lips. "He'll be fine."
She closed her eyes to try to gain control of herself again.
"Has Stefan been any help at all with getting you blood other than Matt's?"
"He's trying…" she began, looking at him again.
"He's trying to distract you," Damon interrupted.
Elena hesitated, "Distract?"
"He took you out for 'fun', didn't he?"
Elena tilted her head. "Yeah, so?"
"Was it fun?"
"Yes," she answered slowly, wondering where he was going with this.
"Did he do anything else for your today?"
"Yeah," she said, uncertainly. "He talked me out of trying to kill Rebekah."
Damon shook his head. "I guess I'm not the only one who saves Barbie Klaus. Did I mention how much I regret saving her from Rick-the-Vampire-Hunter?"
Elena shook her head. "He was right Damon. I can't give in to the rage – the guilt would kill me."
Damon snorted. "Saint Stefan."
Elena felt a sudden need to defend him. "And, when we figured out I had werewolf venom in me; he brought Klaus to me, had me drink his blood."
Damon's face became concerned, but it was gone quickly. He managed a smirk as he said "That's Stefan. Slugs me because you drink some of my blood, but he takes Klaus to you to feed from."
"That wasn't it, Damon," Elena said, shaking her head. "He was saving…"
"I know," Damon said, putting his finger to her lips again. "And I'm glad that he did it, and that Klaus did it. But it gives us one more thing in common."
"What?"
"We both had some of Tyler's venom in us, and we both have some of Klaus' blood in us."
Elena lowered her eyes again as she processed this. He was right.
"And after all of Saint Stefan's 'help', you were still hungry enough to kill the quarterback."
She flinched, but Damon pulled her chin up so their eyes would meet again. "No more, Elena. Until you have control of yourself, I'll be with you every time you feed."
She didn't want to say it; but Elena was, again, grateful for and amazed at what Damon was willing to do for her.
These little tidbits have the very likely premise that Elena continues to lie to herself about her feelings for Damon. Another, called "The Hope and the Need", has the premise that Elena has accepted her Damon feelings, but is lying to Stefan. Check it out, if you dare (or are bored, or whatever…)
