Thoughts on Rebekah and Stefan, Kol and Mollie, Dallas and Freya?
Honestly, they all seem happy, none of them seem to hide anything from each other. Besides Rebekah's secret wish, though her insecurities keep her from voicing them to her partner. She should perhaps talk to him about that.
Mollie and Kol seemed to have only had a small hiccup after Kol was tortured, but they seem to be edging back into the flow of their relationship and how it was before. I only wonder how this relationship will go in the future. Kol is immortal. Mollie certainly is not. If they marry, Kol will have to watch her waste away and die. And then watch her daughter do the same, while he remains trapped in his youth.
On the outside, it would appear that Dallas is too controlling of somebody that cannot be controlled, but if you explore the dynamic of the pair it works for them, strangely enough. I don't think Dallas took Freya's premonitions seriously enough, however. He is too critical minded. I think their greatest challenge will be facing the fact that Dallas wants to be a father, despite what he might say to the contrary.
