If I feel I found my DAD who we had lost somehow 20 years back when we were children, I will press my brother to join me and go asap to meet him.
If he argues we do not need dad, as Mr. abc has been more helpful than our DAD, then sure I will be unhappy with my brother. But that is my limit, I shall try persuade that dad is DAD, he is our father, no Mr abc can be his replacement. I will also do little coercion, all in spirit of brotherhood.
