Brogan did say when they bought the house that they could use of the rooms as a nursery if they had children.
But... I think the pandemic has made a lot of us around Brogans age reevaluate. She has probably felt she is missing out on travel time and realised this is what is important to her and what makes her happiest.
I sort of felt the same and then a couple of months ago it was like a switch flicked and I felt like I NEEDED a baby now, so she may get the same, but I can see why at the moment her priorities may have realigned over the past year.
I do think if Benji wants kids though it will cause an issue, and I would hope she wouldn’t change her mind just to please him because I feel she would end up resenting the child when it stopped her from just doing what she wanted 24/7.
