Caleo Head-Canons
Leo would definitely stop flirting in such a romantic way with other girls after they start dating
Leo would watch Disney movies with Calypso
Why Disney movies? Because it reminds him of his younger, happier days - the ones he's having now, because he's FINALLY dating Calypso
They wouldn't have much PDA, because Calypso is too uncomfortable with it
To people who don't know them, they would think that they're enemies
Leo would give Calypso a phone he made himself - the very 1st one -
Calypso's the brains of the two
Calypso would make ancient Greek dishes for just the two of them
Calypso would make all of Leo's clothes fire-proof
Piper would totally attack them (verbally) if she caught them making out; Piper would also take a photos for blackmail and just to have a picture of them
Leo would propose either of these 3 ways:
^Above^ | Leo proposes in Spanish to confuse Calypso and after he took out the ring, she understood and said yes (Calypso would learn Spanish after that
^Above^ | Leo tosses an apple to her, and after a second she understands and says yes
^Above^ | A conversation something like this:
Leo: You know, you don't have a last name
Calypso: Yeah, so?
Leo: Well, people might get suspicious; but, you can always change it Valdez! *winks*
Calypso: *Tosses a frying pan at him*
Leo: *Puppy dog eyes*
Calypso: Alright, alright *Sounds like she is groaning, but she is internally smiling the brightest smile the world has seen*
