Season 2 Speculation...

Since they scrapped most of Elfstones of Shannara for the first season, how much do you think the second season will adhere to Wishsong of Shannara? Or will they make everything up?

Maybe if Wil saves Eretria (spelling?), then they marry and the show skips to their children with the Wishsong and proceeds from there? That would be awkward pacing, though. Or perhaps Eretria has the Wishsong, since she had those weird markings?

Also, it's been over a year since I saw the show, and longer since I read the books, so apologies if I'm a bit rusty.
