Check out What TwilightExaminer think about Breaking Dawn's the Volturi extra scene..
What Aro means by (They have something I want")
what does he want, exactly? there are a couple of theories.
We were all warned early on to stick through the credits of The Twilight Saga: Breaking Dawn - Part 1 for an extra scene . . . And so we did.
In the extra scene, which features the "Volturi," "Aro" (Michael Sheen) is presented with a birth announcement, it seems, which indicates that "Carlisle has added a new member to his family."
"Caius" (Jamie Campbell Bower) interprets this to mean that he's strengthening his army - which is a bit strange, since in The Twilight Saga: Eclipse, it was "Caius" who "Jane" (Dakota Fanning) thought would be most interested in the news that "Bella" hadn't yet become a vampire.
Note: The "new addition to the family" isn't "Renesmee," since they only learn of her existence thanks to "Irina's" squealing (which happens after she sees them playing in the woods much later on).
"Marcus" (Christopher Heyerdahl), meanwhile, thinks this means the riff between these two covens has come to an end.
Not just yet, according to "Aro." "They have something I want," he teases.
So what does he want, exactly?
Well, there are a couple of theories.
Some have predicted it has to do with "Renesmee," but that couldn't be (see above). Others have suggested it has to do with "Alice" and "Edward," who he's asked to join his group as early on as New Moon. He's a collector of gifted vampires, after all. Which leads to the third theory that what he wants is "Bella," who he has before noted "will make for an intriguing immortal."
I'm split between the second and third ideas. What do you think he wants?
