He just… doesn’t and I don’t think it’s because he can’t.

I think it’s because he won’t. based on TamlinxRhys's sister being old lovers theory

I like to believe Rhys’s sister the one we never got to meet and the only one Tamlin truly loved taught him how to fly. That maybe she laughed while dragging him through the skies, told him to stop snarling and just enjoy it.

That flying was their thing. Not roaring through the skies to look powerful. Not to intimidate. But just… for joy. For freedom.

And after she's no longer here, Tamlin stopped.

Because what’s the point of flying when the person who made the sky feel alive is gone?

What’s the point of soaring if it just reminds you of what you lost?

He could fly.

But he chooses not to.

And seriously, guys you’re telling me this ancient, great warrior High Fae who’s been alive for over five centuries never thought of doing the thing Feyre figured out in like... a few months?

It doesn't make sense. He’s not dumb. He’s hurting.

He doesn’t fly not because he never learned how or never thought of.

But because it doesn’t feel like his sky anymore.
