Why did that guy explain everything to her when her boyfriend was right there and could do it himself? Those weren’t his secrets to share.
Also, grandma is being pretty gross. On your first meeting she didn’t introduce herself and just came out and said she’s not “allowed” to breed with her new boyfriend.
I guess granny assumed that she knew all about her boyfriend’s family and was chasing him for his money? He doesn’t even seem interested in being the “successor” or whatever anyway but this is quite a mess.
The good thing is that he is a straight talker who can probably explain things well… as long as she can get over the fact that he concealed all this in the first place.
