According to reports, C.J. will interact with Amber and Stephanie. Key among C.J.'s return is the future of Insomnia, the coffeehouse he owns.
Cain's return is scheduled to last just two days, but, as soap fans know, anything is possible in the future.
Cain first aired as C.J. in 1998. He was last seen on-screen in November 2007. His first return appearance is slated for December 21.
