Did Loki just explain the bonkers plot of Doctor Strange 2?
 that was first inducted into the Marvel sphere by Into The Spider-Verse in 2018, a surprisingly brilliant, Oscar-winning animation from Phil Lord and Chris Miller. In that movie (which was not part of the MCU) a bunch of alternate reality Spider-People accidentally wound up in the same place, causing delightful chaos, thanks in part to the variously entertaining iterations of the web-slinger (John Mulaneys Spider-Ham being a standout). Rick And Morty, on the other hand, has been playing with the multiverse since it first began in 2013. In an early episode, its titular characters  a mad scientist and his grandson  were forced out of their reality into another one just like it. They had to kill their counterparts and bury them in the back garden. It was as grim as it was funny. (Not for nothing, Rick And Morty writer Michael Waldron is also the showrunner of Loki.) We already knew this was coming. Spider-Man 3 has long been rumoured to see Andrew Garfield and Toby Maguire reprise their roles from previous 21st-century iterations of Spidey, and though Garfield and current Spider-Man Tom Holland have both vigorously denied that this is true, smart money is still on this coming into fruition (notably, JK Simmons reprised his role as angry newspaper man J Jonah Jameson at the end of Far From Home). WandaVision hinted at it with the stunt casting of Evan Peters as fake Quicksilver, dragging him over from the X-Men universe in lieu of the Aaron Taylor-Johnsons MCU one. As soon as the Avengers started playing with space and time in Endgame, it was only a matter of time, really.
