Jon Snow is currently dead. Without posting spoilers, there was a character on the show (Beric Dondarrion) who was brought back to life several times by a red priest (Thoros).
And red priestess Melisandre conveniently returned to Castle Black right around the same time that Jon Snow was murdered by his Night’s Watch brothers...
You forgot The Mountain.
