I saw on Facebook that Mitch Jarvis and Katie Webber had rejoined the cast of RoA, though there was also a picture attached of the understudy board stating "At this performance the role of Lonny, usually played by Genson Blimline, will be played by Mitchell Jarvis". Is he only in the show temporarily?

He's been tweeting randomly when he's been on. He was in as recently as this past Monday. Not sure if he went on last night.
