> bað hann þá muna syni sínum ef svo bæri við það er með þeim var vel.

I'm not sure about this myself. If 'ef svo bæri við' = "if that comes
to pass" (MM & HP "if anything happened"), then does the rest refer to
what is to be done to help his son, or is it an appeal to the
friendship that exists between Runolf and Otkell?
