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.

Which is admittedly what could be said about any event in any game ever, really.
Star Trek Online? You know, the guy that got a whole write-up just for the fun of it about how he might indicate a crossover between two universes of Star Trek?
