Prince Harry revealed a cute detail about his four-year-old son, Prince Archie, in his new Netflix docuseries Heart of Invictus.

“When I talk to my son Archie about what he wants to be when he grows up, some days it’s an astronaut, other days it’s a pilot,” the 38-year-old Duke of Sussex says in the docuseries (via the New York Post). “But what I remind him is no matter what you want to be when you grow up, it’s your character that matters most.”

If you didn’t see, Meghan Markle and their two kids, Prince Archie and Princess Lilibet, did not attend the Coronation of King Charles. It’s been reported that they made three requests of the Palace in order for them all to attend, one of which apparently involved Archie.
