One of my current hunches as to why the events of Sinmas won't go well for Blitzø and Stolas, is because of the former. And Via doesn't like Blitzø. And because Via and Loona where sidelined in an episode that SHOULD have been about them, I don't think Via's views of Blitzø have changed.
Which is why I wonder if an episode or short about the two of them being forced to work together could be helpful. If it were up to me, I'd draw a lot of inspirations from the apology scene from Zootopia. I'd have Blitzø acknowledge that all this was his fault for starting that affair that not only led to all this trouble, but created an unhealthy relationship with her father that brought out the worst in both.
And that when this is all over, she can hate him all she wants. And Blitzø will accept that because the affair has hurt more people then he can count. The next question is, what will Via think?
