It has to be a "soap" thing.....I remember on Guiding Light...that wonderful, but wild Reva Shayne. As a teen, quite the thing for Josh, but ended up having a child with his brother, Billy. She was only 16, baby adopted. (this was told in back story) Years later, Reva returns to town, takes up with her soulmate Josh. Alas, troubles, they part.....and next thing, she is married to his FATHER. As years pass, she & Josh are back, having problems, but.....GL went off the air forever with Josh & Reva walking hand in hand down the street together.
On Days, hasn't Sami gone after her sister's boyfriend, Austin? In fact, wasn't Lucas with Carrie & Sami with Austin at one point? Then there was Belle & her best friend, Mimi, exchanging husbands (Shawn & Philip). Kate was married to Stefano, & his son, Andre. Kayla married Jack, and then his brother, Steve. JJ had long time girlfriend, Paige, but had affair with her MOTHER, Eve. And then there was that bad idea of putting Shane & Kayla together after it was thought Steve was dead. Kim had left Shane, moved to CA....which is where mercifully, nurse Kayla went, as well, & became a doctor..
