That's like that Lalafell just outside Revenant's Toll (near the Coerthas zone) that a couple patches ago would say, "Only one way to find out..." when you walked up to him. Ever since 2.2 he's been mining away on the same spot just out of reach, and another NPC is watching him wondering who mines while wearing full plate (even though the mining Lala does not appear to be wearing plate armor).

What is the thing he is trying to find out?!
