Q (and the Continuum) make a lot more sense if you assume they actually have no real agenda and everything they say or do is just to screw with the lesser races.
Q: "What do you want to do today?"
Q: "I don't know, what do you want to do?"
Q: "Same thing we always do - confuse the hell out of lesser beings!"
Q: "But how? We tried the 'You're on trial!' thing, and we tried the 'Only you can save the universe' thing...what now?"
Q: "Hey, I know! Let's pretend we're having a civil war!"
Q: "I love it!"
I prefer to think that everything
they say is a lie, especially when it comes to speaking about themselves.
