The actress posted a photo of one of her scripts on Twitter with the accompanying text, "A day in the life of a soap actor. Say 'soap-y' I dare you" and hashtags "#notthewholescript #onlymyscenes."
A first airdate has not been announced, and McCullough revealed only that it would be "sometime this summer." Likewise, the details of what brings Robin back to town and how long she'll be sticking around are also being kept secret -- but that hasn't kept fans from speculating.
McCullough exited General Hospital earlier this year on the show's March 4 episode.
