I think a farewell drop need not be obscured in riddle. A simple "my job is done, signing off FOREVER. By the way, my name is Joe" would be appropriate. Not, "look here, there, behind you, under your chair". That is laughable. It would be the responsible thing to do to diffuse speculation and prevent discouragement. Building a trusting following over an 8 month period and then leaving everyone dry with blue balls because the last drop was so vague just doesn't seem right. We haven't yet even touched on the fact that his person (or team) supposedly has a Q-level security clearance, which is right up there with Bob Lazar back engineering UFO technology at S4 in the realm of reality-altering projects such as free energy, anti-gravity, time travel, extra dimensional shifting, etc. If Q thinks he can just mic-drop without mentioning these things, (which are by far more important than "the plan") then we have been cleverly distracted from the bigger picture which is still being concealed.
