Question: What happened to Kevin?
Answer: I think I found the quotes on quotes.net. Kevin's family got angry, and they don't believe him about the cigar that Michael has. Kevin's only friend is his imaginary friend named Horseman, and Alfred said, "You're extremely bad, Kevin." Kevin might be in military school or something.
Question: Michael is in the year 2023 (following the timeline of the movie), and then upon learning of Morty's true identity, he asks to be taken to a good place and then he appears at his son's wedding. Everything I've read about this movie says that the wedding is in the year 2030 (one article said 2033). But where in the movie is the proof that seven (or ten) years have gone by? His kids look the same as 2023 and the wedding is simply "a good place" he was taken to. Where's the evidence showing a future year?
Answer: We know significant time has passed, because Michael's hair turns fully gray. The exact number of years is unknown.
Answer: Kevin tries to tell his mom that he didn't smoke the cigar and she doesn't believe him. Kevin argues with his family, and he only had a friend named Horseman, the imaginary friend. Kevin's dad said, "you're extremely bad, Kevin!" Kevin might be in military school or somewhere.
