Turns out William Daniels wasn’t just visiting the Girl Meets World set earlier this week — he was working.

TVLine has learned that William Daniels will indeed reprise his beloved role as Mr. Feeny in Disney Channel’s Greatest Pilot of All Time.

It’s not clear what function the character will serve on the Boy Meets World spin-off, but considering he was photographed in a classroom setting — and given his teaching background — it seems logical that he will be back working at the school now attended by Cory’s (Ben Savage) children (including Rowan Blanchard, who’s playing his titular daughter, Riley).

A GMW source, meanwhile, points out that Rider Strong and Will Friedle — who were also snapped on the set — were just visiting and do not appear in the pilot.
