Well, one possible plot could be that Hans has some hidden motives for kidnapping Elsa. Maybe he wants to use her powers for his own gain, like ruling Arendelle through her magic. He could hold her in a secret location and try to force her to cooperate.

They might meet during a time when Elsa is exploring the outside world more freely. A sudden danger, like a new magical threat, could bring them closer and lead to that kiss as a moment of new - found trust and attraction between them.
