Then again if that old man did not kick the bucket in such a situation this slavery business would just end peacefully.
With that along with the changes the dead of Canute's Brother may bring to the life in the farm just about anything is possible.
They could get their chance to freedom cut off... Or they could have to go tell their master his father is ill and hence follow after him... Which could lead to Thorfinn meeting Canute.
Considering how Canute and Thorfinn have been going in complete polar opposite in term of finding inner peace since they last met It could be an interesting encounter.
