There’s always the possibility that something was misunderstood or misinterpreted, but it’s not too much of a stretch to say that the character will be showing up when he’s been sneaking about in NPC form. We’ll just have to wait and see, but odds seem high that a crossover will indeed be happening, to the delight of some and the chagrin of others. Which is admittedly what could be said about any event in any game ever, really.
