Previews are inplying what I have suspected for a long time

Anybody that has been watching OLTL for few years, knew that Rex's father would either be Carlo Hesser or Mitch Lawrence. Mitch being the obvious as he is Jessica's bio father and Natalie was married to him briefly. No surprise that it is Mitch Lawrence. That just makes Rex and Jessica brother/sister...at least they never had those two "hook up"! The writers had best make sure that as they constantly changed parentage for the characters.. they'd better make sure who they have "hook up" with whom!!!
