I do wonder like, what can you even do as the family in this kind of situation? Assuming you want to be generally positive and supportive family, stuff like completely separating them seems kind of cruel, and it's not like either of them are really old enough to fully grasp a frank discussion. Being concerned is obviously reasonable, taking action that doesn't backfire or do some harm seems a lot more difficult.The grandpa was super quick to catch on. Also, while they do seemingly have some concerns they also seem to be okay with it as well
