There's a Big 'Boy Meets World' Reunion on 'Girls Meets World,' a.k.a. Christmas Came Early! — PHOTOS

Another Boy Meets World reunion is set for Girl Meets World , and this time it's a big one. On the upcoming Christmas episode, "Girl Meets Home For the Holidays" (airing Dec. 5 on Disney Channel), Shawn (Rider Strong) will join the Matthews family for dinner, and that's not just Cory (Ben Savage) and Topanga (Danielle Fishel). Almost the entire clan will be there, with Cory's parents Amy (Betsy Randle) and Alan Matthews (William Russ) joining along with their youngest son, Joshua.

If you're having trouble remember Josh, it's probably because he was born in Season 6, which aired in 1999. He's a teenager now, and will be played by Uriah Shelton. No word on why little sis Morgan (Lily Nicksay) and older brother Eric (Will Friedle) aren't showing up for the pow-wow, but there will still be plenty of fun with Cory and Shawn back together. Apparently Shawn sees a lot of himself in Cory's daughter Riley's (Rowan Blanchard) best friend Maya (Sabrina Carpenter) and bonds with her and Riley. Click through to see all the holiday reunion fun!
