"Alice Will Be Alice."
I always loved Alice, right from the first time Bella met the Cullens in Twilight. She always struck me as a girl with so much personality! Personally, I think her powers ("psychic") added to that. Her personality, that is. In Twilight, Alice was a minor character. I think that as the Saga progressed, she became more and more important. From Twilight: "Alice had a bit too much fun fabricating evidence."
As for Alice in New Moon, you really don't get a lot of her there, except for at the very end, when she comes back, thinking Bella's dead. Well, I take that back. You do get a good look at her personality when you "see" the decorating she did for Bella's birthday. Yikes!
Alice in Eclipse. In the beginning, you get Alice's reaction to Bella's freedom.
Bella: "Alice, whatever you're thinking, I doubt I'm that free."
Alice: "Free is free, right?"
Bella: "I'm sure I still have some limitations... like the continental U.S., for example." The others laughed, but Alice grimaced in real disappointment.
I thought that it was cool how when Jasper was training them (the vamps and the werewolves) how to fight newborns, Steph showed her fans exactly what Jasper was trying to show Bella: she may be small, but you don't need to worry about her.
And:
Edward: "Alice, please don't. You're about to make my life so much harder than it has to be."
...
Alice: "Bella, do you love me?"
Bella: "Of course I do!"
Alice: "...How much do you love me?" ... "Let me plan your wedding."
Bella: "Alice!"
I think a lot of the best shows of Alice's character are in Breaking Dawn. You start out with her crazy decorative side with the wedding, from the decorations themselves to "decorating" Bella.
At the wedding:
Alice: "I'll tell her where you're taking her, Edward. So help me, I will." Awfully small. Hugely irritating.
Then, you get Alice when Bella and Edward come back. And then, when Bella wakes up. Her reaction to the werewolves. Her setup with the forger. Her return. Like I said, I think Alice's character really evolves in Breaking Dawn.
We love you, Alice!
