Addie will be there, reluctantly and probably in impractical footwear. There's plans in the works for her to encounter the wendigo itself down by the river and get Hero'd by her dearest brother... but surrounding that point she's here for the taking!
John will go on the trip, but not especially enthusiastically. Enthusiasm is against his religion.
Holly will be there for the fun, she likes camping out and socializing but also will partly be going because she feels like she can be of some use if/when shit goes down. So if anybody needs a clear-headed responsible type, she's your gal.
Verona loves the spooky and wouldn't miss it. She's still fairly nonfunctional as an independent human being, so she'll probably gravitate towards some big personality and hang with whoever would take her on... one of these days we'll start working her towards some independent thought, I swear...
