The GH audience is talking and tweeting about the possibility of John McBain and Sam McCall being brother and sister. They have this connection that she can’t put her finger on. We as the audience all now that it was back on Port Charles when they were vampires together. In my opinion, I highly doubt that will be brought to light on General Hospital, so I am assuming that if they keep up with this “connection” stuff, it will be family relation as opposed to romantic or anything else. Then will we finally find out who Sam’s Father is? GH fans are expressing these thoughts on Twitter. What do you think? Please leave a comment below!
