Well we’ve seen Regina in true love, seen someone have a crush on her, seen her in a coercive/abusive thing with Graham and a loveless marriage too….so kind of what’s left to explore?
That’s why I reckon her next guy could well be her eventual endgame. K&H have said before that they intend to explore the idea of loving again once you’ve lost your (first) true love. Setting up a relationship for Regina that will be genuine, functional, positive and long lasting would be showing that hopeful, loving again story. We know she’s gonna have that story at some point, because we’ve seen FrankenDaniel tell her to do it…
Regina: But I love you.
Daniel: Then love again.
…If they’re gonna have Regina honour Daniel’s final wish for her, I reckon they have to ultimately give her an actual, loving, healthy relationship with a standup guy. Daniel loved the good person she used to be, so I believe there will be someone who will be able to bring that out in her again. Eventually. Even if the relationship doesn’t start out easy and love at first sight. If they introduced such a character now, they’d have time to show the relationship growing and Regina changing for the better as she comes to terms with having a new love in her life.
