I see what you are saying. To me, he wanted more sons… I have no doubt that he loved Lagertha, but had to pursue that goal above all else. We look at such things through a very different lens today.

No.. the choice was hers, duh

He didn't leave her, she left him, remember?

Exactly, nicely put

Remember Lagertha came to Ragnar's aide to rid Kattegat of Jarl Borg, I can't imagine he wouldn't return the favour.

I agree, that should have been a significant moment for both characters. Instead it felt really contrived and non-climactic.

It is Þorunn (Old Norse), not Porunn. You think she's developed? Can you tell me where she's from, or any of her history at all? I don't dislike her, and I get that you like having a fierce woman as a character, but you can't really believe her character has any depth or development.

Thorunn? I think she's a very boring, undeveloped character so far
