"Since the word is out, yes!" Branson announced on Twitter. "Shot my first day yesterday [Friday, May 18]. Happy to be back in the GC."
After wrapping his AMC run, Branson headed to Guiding Light in December 2008 to play the role of Shayne Lewis. Branson remained with the series through its finale in September 2009, and in 2010 won a Daytime Emmy in the Outstanding Supporting Actor category.
Branson first appeared on The Young and the Restless in June 2010. His most recent appearance was in February 2012, at which time Ronan left Genoa City to work on a secret case.
His first airdate will be June 26. A show rep declined to comment how long Branson will be sticking around, but a show source hints that Branson's return will be tied to the exit of another character.
