Well, it depends.
If it were Edward i would freak and force him to marry me against his will. If it were anyone else i would freak out and get autographs.

Ummmm..that`s a hard one-I would probably forget how to make noises come out of my troat LOL After those awkward few second(if the cast member is not gone already) I would just smile my dazzling smile LOL and say I`m a big fan-but we gotta remember they`re people just like us so-just be happy you`ve been in touch with someone who impersonates one of THEM-Twilight`s characters:)
if it was Edward,Jasper,Emmett
1.pass out
2.wake up,kiss(and/or rape them...lol)
3.pics& photgraphs
4.still hair, & some clothing
5.scream i love you
6.pass out again
then later at home i wll be pissed cuz i didnt kidnap them and hide them in my basement
if i met emmett id go up to him and be like hey im a big fan of u and think ur pretty hot and ask for a picture of us together and ask for an autagraph then go out of his sight and die
