Is King’s Father a bad Dad?

When I first watched this scene, I found it disheartening that The Titan didn’t think about his son, and that Luz had to ask directly if he had a message for him.

But after a bit of thinking, I had a thought. While it’s true that King has missed his father for his entire life, The Titan has been watching and been with him the whole time. So when Luz tries to ask about unfinished business, he jokes about “Sending the Owl Lady his regards.” and Luz has to remind him that King hasn’t had his father in his life, even if The Titan had King the entire time.
