I love Rex and Adriana. And they do remind me of JT and Colleen. I mean, think about it. Rex was this older bad guy who befriended a younger good girl, Adriana. And they fell in love. The difference between JT/Colleen and Rex/Adriana is that Rex has been the one trying to get Adriana to be with him and Adriana was seeing Duke while Colleen was the one trying to get JT to be with her.
I am right there with you there. I loved Natalie and Cristian but once John came on, I fell in love with John and Natalie. I think I've decided I want John and Natalie together, but then again I still enjoy good Crisalie moments, lol. So I don't know. It makes for an interesting storyline though.
