Dane probably always knew Grayson was bigger, but knowing it ≠ seeing it every day.
then they live together and he catches their reflection in the mirror like… why is this man SO big.
You knw what I donno abt the triplets but Grayson is def having a daughter. There's no way this guy is not a girl dad. I can already imagine him calling his daughter 'little princess ' 🥹 (Dane's def gonna carry his son like this lol)
