I started this fight when I was under powered, and when I started getting my [censored] handed to me. I fled the area to return when I was better equipped for the fight. Upon my return to the fight. I was able to dispatch the enemy and he fell to his knees, but that is all that happens. I have watched videos of the fight to see what is suppose to happen, and his son does not run to his side; nor does any dialog start or dialog options appear.
I have tried the following:

1. Leaving the area and returning
2. reloading my different saves
3. fast traveling to a different location and returning

Nothing has worked.

This issue has seemed to have either worked itself out or I discovered a work around. I completed the Asgard quest line and returned back to England and went to try the fight again and I was able to finally completed the quest/fight.
