Re: A Song of Ice and Fire Novels
--->Jon Snow warged into his wolf.
----> Men of the Night's Watch gonna be like " And now his watch has ended"
----> Mellisandre revives his body
----> Jon wargs back into his own body
----> Because he warged in the wolf he will be just Jon and not unJon
-----> He has not duty anymore to the Night's Watch and he can march towards Winterfell
This makes the most sense here.
