It’s not surprising to see that Kathryn Winnick would be a little reluctant to take another role on network TV after her character on House was shown looking fresh as a daisy after everything she'd been through. While it's not so bad, in theory, it's not too realistic to be getting punched in the face, but immediately after appear as though there was no fight at all.
Luckily, her character, Lagertha, on Vikings went through it all and more, and had plenty of blood, scars, and more to show for it. She was ultimately killed off in the final season, and while Winnick said her exit was harder than she thought it would be, it was still bittersweet.
