Rumorville:  There are all kinds of rumors and speculation flying around about who Kristen Alderson,  Michael Easton, and Roger Howarth's new characters may turn out to be when they return to General Hospital in new roles.  Some the most most popular items:

Alderson as Scott Baldwin's daughter, Serena. (Serena is the daughter of Scott and his wife Dominique, who passed away. Lucy Coe was their surrogate).

Michael Easton as a long lost descendent of Caleb Morley, who comes to Port Charles to investigate Stephen Clay and his family history.

Howarth as a....Cassadine? who grew up sheltered away from the evil influence of his family.  Or maybe a Quartermaine?

Time will tell....
