So is the implication from the clank of metal armor and her statement about hope in the epilogue that Anduin is staying behind in the Shadowlands not just to heal from his trauma, but to accompany her in saving the souls too?
Or is that supposed to be Nathanos? I just generally don't associate him as much with the "clank of armor," even if he's in what could be interpreted as mail - he's more based around being fleet and ranger-y. It also describes it as "unexpected" mere sentences from her thinking resolutely that she'd find him.
But hey, if it means getting rid of Anduin for longer, I'm good.
EDIT: Garithos and Arthas are also candidates but the former is probably not even a name known by the majority of present Blizzard staff and the latter is in my anima reservoir.
