Ok so, I'm very bored right now so I made up a person who, if Via and Kristina never got together, would be with Via. (Provided that they left the island)

If they left the Island, here's how they'd meet:

Via would go home first, saying good bye to her Island Family. Then, after an emotional reunion with her family and her best friend, she'd get down to the local café to see some of the workers there, as she's always go with her best friends Mum (before she was taken.) Then, they'd meet Emily, the daughter of one of the workers from when Via still lived here. Emily now works at the café. The pair would get along well and would become good friends. After a couple of years, Emily would ask Via out and they'd start dating. On Via's 25th Birthday, Emily, who would also be 25, would propose to Via. Via would say yes and all of her Island Family would be invited to the Wedding. They'd remain happily married and would adopt a little girl, calling her Francesca. 'Frankie' for short.
