I don’t think Carlisle would like imprinting at all. IMO he would find the loss of free will that comes with imprinting absolutely horrifying.  He’s only been able to create the life he has for himself BECAUSE his free will trumped vampire instinct.  So this is something I wish would have happened in Breaking Dawn.  

“Jacob, may I have a word?”

Jake looked up from where he sat on the floor playing with Nessie to see the leader of the Cullen coven standing in the doorway. His expression was pleasant, patient even, but his posture signaled this was not a request to be declined.

“Sure, sure,” Jake said, standing up. “Don’t miss me too much, Ness,” he teased, ruffling the girl’s hair.

“Outside,” Carlisle said, nodding his head towards the door. “I would like us to have a modicum of privacy.”

Jacob shrugged and followed the blond vampire out into the Cullen backyard. They walked in strangely companionable silence for a mile or so into the woods before Carlisle finally spoke.

“This imprinting business…”

“Look,” Jake said, throwing his hands up in the air. “It’s not something I can control. You know it’s nothing creepy. Edward would have had my hide months ago if—”

“It’s not that,” Carlisle said with a shake of his head. He stopped and turned to face the young man. “This is not what you want.”

“Huh?”

“Bella made a choice to join us. She chose immortality, she chose a semi-nomadic existence where we must pick up and leave every few years, move from town to town… it is a very isolating existence, lonely even when surrounded by family. But she chose it. You did not. You had the choice made for you by this imprinting magic, and I am concerned that this is not at all the life you would have chosen for yourself.”

“Well it’s kind of a moot point now, isn’t it, Doc? I can’t leave Nessie.”

“Why not?”

Jacob blinked. “Because I can’t.

“Why not?”

“You don’t understand the pull, it’s like steel cables, I can’t—”

“Do you know what London was like in the 1600s, Jacob?”

A hint of the old Jacob returned as he rolled his eyes and smirked. “Not really much of a history buff, Doc.”

Carlisle chuckled lightly. “It was an incredibly crowded place, and one of the largest cities in the world, with houses and shops crammed close together, in many cases built on top of one another.

“While I was undergoing the transformation, I hid in a stranger’s root cellar. When it was over and I awoke to this second life, I was quite literally surrounded by humans. The scent of them set my throat ablaze, the sound of their beating hearts called to me, and there was nothing I ever wanted more in my existence than I wanted human blood in that moment. So yes. I think I do understand what you mean by a pull to a certain extent.”

“What’d you do?”

“I ran out of the city. It went against every instinct I had as a vampire, but once you get far enough away from the pull, it becomes easier to ignore. Your mind clears. You can make your own choices—the choices you would make as a man, rather than the choices made by your instincts as a vampire.”

“That’s nice for you bloodsuckers, Doc, but no wolf’s ever broken an imprint before.”

“And no ‘bloodsucker’ had ever become a doctor before,” Carlisle countered softly. “If there is anything I have learned in my long life, it is that something is only impossible until someone accomplishes it.”

For the first time since he had looked into infant Renesmee’s eyes, Jacob felt a stirring of his old self.  His own wants and desires, rather than hers.  It was faint, but it was there; beneath the love-devotion-obsession-protection-Renesmee-Renesmee-Renesmee, there was the old Jacob who wanted to live a life free of monsters and magic.   If vampires could learn to resist the lure of blood, why couldn’t a wolf learn to resist the pull of an imprint?  He was the heir of Ephraim Black—if anyone was strong enough to do it, it should be him.

“Are you trying to get rid of me, Doc?” Jacob asked with a wry grin.

Carlisle smiled back.  “You should live a life of your own choosing, Jacob.  And you will never be able to do that here.”
