TwiCrackers, meet JD Pardo (rawr!) who is confirmed to play Nahuel in Breaking Dawn!
According to JD's IMDB he's previously appeared in mainly TV series from The O.C. and Veronica Mars (woah, flash back!) to 90210 and CSI Miami more recently.
If you'e a lil rusty on the book, the Twilight Lexicon's handy dandy bio:
I'm assuming he's meant to look the age of 17/18 - as in the oldest Rensemee will also look - but with JD being 30 we can all drool without the guilt.
Full Name: Nahuel
Status: Hybrid Vampire/Human
Date of Birth: 1850’s (BD38)
Originally from: Chile (BD38)
