The one in which the point of view goes to someone else, Stefan gets the shock of his (un)life, and everyone lives happily ever after (for real, this time).
Bella Cullen loves her family and her part in it; she's a mother, a daughter, a sister, and a wife. She takes these things seriously, and when one of her own was hurt, she freaks out (just a little). The battle with the Volturi was bloody and involved a lot of fire (Stefan wasn't kidding when he said he was good with a flamethrower. Damon wasn't half bad either.)
She's the first one to find Stefan as he writhes on the ground, venom surging through his veins, eating him alive. (Bella might have screamed.) She gathers him into her arms and races back to the clearing ("Carlisle!") Some of her other family is reattaching limbs and Damon is scorched, but he runs when he sees Bella's cargo. ("What happened?" "I don't know, I don't know!") Then Carlisle is there, looking over Stefan ("The venom is spreading faster than I've ever seen in my life" "What's that mean? What's happening to him?" "I don't know")
Some of their witnesses leave but some stay (the Africans and the Denali Clan) and everyone goes to the house. Bella sets Stefan down on the table Bella change on with Carlisle looking him over, and Bella and Edward hovering at the door, and Damon is standing next to Stefan, gripping his hand tightly in his own. (Rose has to leave – she can't watch another person go through this and she needs to find Nessie.) Emmett goes with her, and Alice and Jasper are downstairs, reattaching Jasper's left arm. Esme is with them.
Bella settles in for long haul.
"The sixth of January, 1482, is not, however, a day of which history has preserved the memory. There was nothing notable in the event which thus set the bells and the bourgeois of Paris in a ferment from early morning. It was neither an assault by the Picards nor the Burgundians, nor a hunt led along in procession, nor a revolt of scholars in the town of Laas, nor an entry of "our much dread lord, monsieur the king," nor even a pretty hanging of male and female thieves by the courts of Paris. Neither was it the arrival, so frequent in the fiftee-"
Bella freezes in her reading. There. His heart is slowing down. "Carlisle," She calls and then Stefan's heart stops beating altogether. Damon sits up next to Bella, leaning forward. Carlisle and Edward appear in the room, and everyone stops what they are doing downstairs. Bella can hear Rosalie explaining to Renesmee that Uncle Stefan is waking up.
Bella hopes he is.
"Stefan," Bella whispers, and his eyes begin to flutter. Stefan has grown even paler and more beautiful in the night (for his turning did not take the normal three days – though his turning was anything but normal). Everyone is prepared to see brilliant red ruby eyes on Stefan's face, and so they are shocked to see something entirely different.
His eyes are emerald green.
(The venom has enhanced everything about Stefan's vampirism – Bella wonders if his bloodlust will be greater as well.)
There are gasps as Stefan blinks and sits up (with such speed!) and asks, "What happened? I was bitten –" Stefan is searching the room, his eyes frantic. Damon slips to his side, ("You're okay")
They explain everything about this to the best of their knowledge – not that they know much. (The venom which normally corrects and fixes everything in a human, overtaking their blood, has enhanced Stefan's abilities and features – he is faster, stronger, more beautiful, eyes brighter than before. It's a bit much to take in.) (Stefan wants to try out his new speed.) He can smell Renesmee downstairs, but she's not appetizing like Edward feared she'd smell to Stefan (though Jacob does smell more rank, now).
Stefan checks to see if his tattoo made it (it didn't) and wants to go outside. ("I want to see how the world is different") So Bella and Edward and Damon take him. (They race and wrestle and hunt.)
("I bet I'm still stronger than you" "No you're not") (Damon's not.) They go back to the house, and Stefan and Damon loiter in front. ("Are you staying?" "How could I leave now, brother? You'd have all the best adventures without me") (They certainly can't have that.)
