Well to be honest, I have no idea who Leah might be, BUT Seth MIGHT be played by Tyler Posey. It's likely Leah and Seth will be only in the third and forth movie.
Neither of those characters are going to be in New Moon in eclipse im not sure about Leah but seth is played by 'booboo' Stewart
they are not in new moon but Julia Jones will play leahand booboo Stewart will play seth.
well, I am pretty sure that they will not have Leah and Seth in the New Moon movie. they have a few choices for Leah: Brenda Song and Vanessa Hudgens. I am not sure about Who they will have as Seth though.
She's definitely in new moon and i think she is playing Leah no she is not. they will not show Leah or Seth clearwater until eclipse. they r still casting them. i think she would be a good Leah though.
Seth and Leah, harry clearwater's kids. (harry clearwater was the guy who died in new moon).
Seth and Leah turned into werewolves shortly before Harry Clearwater died. Finding out the they were both werewolves, Seth being 14 and Leah a girl, was what caused him to have a heart attack. above and there is proof in Eclipse
Seth Clearwater will be played by Boo Boo Stewart in New Moon and Eclipse.
Leah Clearwater's mom's first name in "New Moon" is Julia.
Harry Clearwater is Sue's husband, Seth and Leah's father, and Charlie's best friend. In New Moon, when Leah changed into a werewolf for the first time, he had a heart attack and died, causing grief for everyone.
No, Julia Jones will play Leah Clearwater.
Harry Clearwater has a heart attack in new moon. (One of Charlie's best friends & Leah & Seth's dad)
Harry Clearwater is the father of Seth Clearwater, he died of a heart attack in New Moon.
