I hope Wan'Dale doesn't leave, but if he does I don't know that I blame Frost as much as some. Wan'Dale probably hadn't been home in months in the middle of everything going on and then he went home and it probably felt great to be with family. Then if his family or others he's close to are pushing him to come home it might be too much to overcome.
My wife and I went back to our hometown at Christmas time and both of us ended discussing moving home in more seriousness than we ever had. It was just so nice to be around family and friends. A couple weeks later and we aren't feeling that quite as much, but we still talk about.
If Wan'Dale decides to go home I can't blame him and people can disagree with me, but I think it's more about being home than it is a statement on Frost or NU.
