Where does everyone get a Nico and Thalia relationship? I'm just wonderin... there's nothing about it in the books...

I know. Besides, Nico is twelve years old.

I don't think Thalia would ever quit the hunters you can see she loves it to much and I don't think you can quit. you can get kicked out I know from the sea of monsters. Thalico? Ew gross!! If she did though it would be appollo or Leo.

Well, none of them, actually.
But if she HAD TO, then I choose Leo.
There's a big age gap for Nico.
Same reason for Apollo.
Another reason: Nico is her direct cousin, and Apollo is her half-brother.
At least, for Leo, they're not direct relatives...

I think nico and thalia would be weird and idk I think Leo could find someone else and idk maybe thailia willl have demigod kids but then Artemis would be pissed with her for quoting the hunters for her brother so idk I kinda just choose randomly :)

Plus thailia would never quit

If she grew some of that precious sense she lost when she joined then Leo
