An ultimate Matthews family reunion featuring some old faces is happening in the finale of "Girl Meets World" season 3.

Writers of the series revealed on their official Twitter account that William Daniels, Anthony Quinn, Rider Strong, Will Friedle, William Russ, Betsy Randle, Lee Norris and Danny McNulty, who once played Mr. Feeny, Mr. Turner, Shawn, Eric, Alan, Amy, Minkus and Harley, respectively, will make an appearance in the final episode of the season, reportedly "to help the characters make a decision."

Aside from them, the two actresses who played Morgan on "Boy Meets World," Lily Nicksay and Lindsay Ridgeway, will also return to join the gang.

On Thursday, Disney even released an on-set shot from the "Boy Meets World" reunion that's happening on the set of the "Girl Meets World" season 3 finale.

While that's good news, the grand reunion could also mean the final bow for all of the characters in the series. This is because there is no assurance yet that the show will be renewed for another season. Also, star Rowan Blanchard's emotional tweet recently seemed to suggest that season 3 could really be the show's last.

On Twitter, the star wrote, "I know as much as you guys do. Filming tonight's episode was very emotional for all of us, so thank you to all of you who came and stuck with us. The family that we have created on our set is something I will truly never forget."

"Girl Meets World" airs every Friday, 8:30 P.M. on Disney Channel.
