"Be careful! You could've flown right into an asteroid or something." Yeah, you're way older than Luna himself and a whole planet very capable of definitely themselves, but still. Is it so bad he still worries about you, like, a lot? Maybe.

But it's better safe than sorry in Luna's eyes, though it may seem overly protective to some. Luna bets their planet isn't the only inhabitable and quite frankly- most fragile thing in the solar system, really.

Besides after the whole Moon Revolution you can't exactly just call it a job well-done and get over it so quickly. Luna especially knew there was definitely still a lotta tension between the moons and their planets'.
