Please release the Carlisle cut. (Aka the meta on his gift)
@therealvinelle, I give up on you.
For a version presented by Aro to a disbelieving Carlisle, see Aro's rambly speech from chapter 7 of Nebuchadnezzar's Dream by @therealvinelle
Per canon, Carlisle's not gifted.
Gifts are extremely rare and the Cullen coven already is extremely gifted for a variety of reasons (namely Jasper and Alice showing up because Alice was drawn specifically to the Cullens)
You have Edward, Alice, and Jasper. Bella being gifted herself is very unusual to the point that Edward thinks he's broken before he finally accepts that Bella herself may have a gift.
There's no blatantly obvious implication that Carlisle is gifted, no offhand mention like even Siobhan's probably gift that's mildly terrifying, and Edward who is our expert on vampires and Cullens never brings anything up.
Carlilse just gets his "goodness" amplified the way Rosalie gets her "pigheadedness"/"beauty" amplified (per Edward, but let's just go along with it here).
The trouble is, if you look at this series entirely too deeply (which this blog does) then there's a lot of things that don't add up.
The Dots Just Aren't Connecting!
Vampires are terrifying to humans.
This is repeated throughout the series. Bella learns this as early as Twilight as Edward informs her how unusual it is she isn't on an instinctual level terrified of him ("Wow, vampires so hot, much wow" is Bella's response to this).
The Cullens are isolated at school because of this, Edward is never approached without Bella because of it (and is very surprised at the hyperventilating waitresses in the Italian restaurant), and people just instinctually don't like them.
Carlisle is extremely well thought of by nearly everyone in the series. Charlie introduces him to Bella as this spectacular family man, despite adopting all these teenagers, who is a literal saint and can't understand why Billy finds him strange.
He works at the hospital where, from what he can see, he's well liked by the staff and the towns people. People go to him as a doctor, this terrifying marble statue of a man, and talk to him about how they have a sinus infection today or ask him to take out their stitches.
Aro gushes about Carlisle for an entire chapter in New Moon when he's supposed to be deciding whether or not he's killing Edward, Bella, and Alice. "Have I mentioned Carlisle?" Aro asks intead.
James, Laurent, and Victoria initially have a weirdly swell time talking to the Cullens despite James being a serial killer who hunts women for sport.
Carlisle has friends from dozens of cultures across the globe, who all gladly eat people. They think he's a little crazy, but they all show up to defend his possibly immortal child granddaughter that his son made by porking a human.
Edward even notes this in canon, that he believes that Carlisle, being so immune to blood, somehow radiates this to the humans so they feel at peace. Otherwise, Carlisle's amplified feature as a vampire his inner 'goodness' whatever that is, so humans and vampires all know they can trust him instinctually.
Regardless, something weird is going on with Carlisle that isn't with the rest of the gang.
Carlisle survives to the present day.
Carlisle, for three hundred years, was a lone nomad who walked all over the place, in other vampires territory, where they had no idea he's not after their livestock, and when he does meet them tells him all about his groovy cardboard diet they have to try.
Nobody suspects him of foul play, of being up to something, and kills him. Nobody gets annoyed with him and kills him.
Not only that, they befriend him.
Amun, a fallen god persecuted by the Volturi who lives on the run, befriends this weird guy WHO LIVED IN FUCKING VOLTERRA. Carlisle gets to see Benjamin, whom Amun is hiding from the Volturi, and has Benjamin show up as part of Carlisle's "not army" of witnesses to defend his mutant granddaughter produced when his progeny porked a human.
Liam at least puts up with Carlisle, if not outright likes him, when Carlisle is from England in the 17th century and Liam is very very Irish and still despises the English.
The Amazonian women leave their lands, which they've never done, to defend mutant hybrid baby.
Alistair, while he does initially live, is a paranoid wracked hermit who leaves his forest, nearly makes himself an enemy of Volterra, and was willing to stay until he wigged out that Bella was going behind everyone's back and thought they were going to lose the fight.
Carlisle isn't just well liked he's--he's the hero of a shonen manga who in the last chapter gathers all the weird one-off characters together that he's befirended through the power of peace no jutsu so they can make a giant tree and save the universe.
Only, Twilight is a shojou manga starring Bella so Bella never realized the shonen anime prequel ever happened.
"Wow these people so nice" - Bella in Breaking Dawn.
And, of course, the fact that Carlisle lived in Volterra for at least 20 years, while very young, presumably bringing nothing to the table, and appears to have had an open invitation to return/left on very amicable terms.
This also isn't even getting to the fact that the Cullens got to sit down and make a treaty at all with the Quileute tribe or that any of the negotiations in Eclipse happened at all.
The Theory: Something's Going on Here
The gift, at its base, is that Carlisle is likable and persuasive. He has no compulsion, he can't make you do anything you really wouldn't want to do (hence the diet failing all the time), but generally you can't help but like him/want to trust him and at least give him a chance to speak his mind.
Rosalie should despise Carlisle, given he's the one that forced this life on her: she doesn't.
Edward took years to leave the diet/family versus immediately, and even then, oddly never resented Carlisle for what he is and became.
The only one who's not weird about Carlisle in some way is Bella, which makes sense, as she's likely immune. She finds Carlisle hot, but generally doesn't care about what he says or give him much time of day. Edward's blathering on, meanwhile, about how his dad is amazing and sexy Jesus. "Wow, he swam to France" Bella says.
This is a surprisingly powerful gift in that it means, well, Carlisle can do things like gather an army of "witnesses" in just a month's time to stand against the superpower of the vampire world. He can hold a position as a doctor. He can make treaties with the Quileute tribe. He can get people to talk to each other, slow down, and listen to him when they should absolutely not be bothering with it.
He can't make them do whatever he wants, read the diet, but he's capable of quite a bit.
Why Hasn't He Figured it Out?
Why would he? This is just how the world works for him.
To Carlisle, people are always reasonable in the end and willing to hear him out, we can all get along if we just try and everyone's good deep down.
It would never naturally occur to him that it's odd people are so nice to him or that they even are being nice to him.
Why Hasn't Anyone Else Figured it Out?
Well, you have characters like Edward who realize something is up, but it's written off.
This is just because Carlisle's so amazing. Edward never realizes that maybe it's because there's something actually up with Carlisle beyond that.
It's easy to see it as just being the way that Carlisle Cullen is. Of course everyone makes nice with him.
As a result, to @therealvinelle and I, it very much seems like a gift that is canon but is also unacknowledged/unknown to every character and not too surprising for being that way.
Carlisle's gift is that people like him.
