Prince Harry has recently been advised to're-learn' a few things, notably those emphasising the idea that "blood is thicker than Netflix."
Angela Levin, a royal analyst and novelist, has issued a warning to the Duke of Sussex.
She explained everything in one of her Express UK columns.
She emphasised the importance of deep family relationships in her post, admitting, "The Sussexes' sprawling estate in Montecito would be the perfect place for a holiday and for the little ones to get to know each other."
"However, given Harry's strained relationship with his brother, there's a better chance of William and Kate taking their kids on an all-inclusive trip to Magaluf," she said.
Ms Levin, on the other hand, is optimistic about the children's future and subsequently said, "Of course, one day the children may find their own way to each other."
"But until that time comes - by which time it may be too late - Harry and Meghan should do something to bridge the gap between the cousins," she says, adding that "William and Kate must, in turn, graciously encourage the bond as well."
After all, "as well as benefiting the children, it will serve as a reminder of family ties - they are all the grandchildren of the King and Princess Diana."
"That alone should be enough of a reminder that blood is thicker than Netflix," says Ms Levin.
"However, who will make the first move?" Given the sour state of circumstances, it's hard to say," she subsequently remarked before ending the conversation.
