In *ST:VOY* "Death Wish," Q (later Quinn) is unintentionally beamed aboard *Voyager*. Not long after, in the dining hall, Q gives his appreciation for the crew rescuing him from the comet. Captain Janeway recapitulates, to which Q says "In a manner of speaking."

What does Q mean by this? Was he actually in a comet or not? Or is something else implied here?
