This crossover is less of a color mix, and more of a Locro, because I have an entire 5 objectives to complete, which is very much on brand with my general hubris; but not something I've done since my Potterfics days. Like, twelve year-old Skyler is cackling madly in some corner of my mind; so I'm having fun, clearly.
5. Weapons and their crafters.
Isabelle watches distracted how Leo's expression changes as the song on the radio does, the old thing had taken him moments to fix up, which she knew because he'd done it while waiting for her to come get him. There weren't any rules in the institute about demigods, but Leo had insisted that it was better to keep their pantheons as separate as possible; but he had agreed to take a look at Isabelle's inventions, a glint in his eyes as he did.
So now here they were, with the old radio Simon asked her to bring, specifying it had to be a broken one no one would miss; it was easy to see why he'd thought it'd be a good idea. Leo looked almost content as his entire body took to moving to the beat, though it was clear he was unaware of it, as he pulled one of the blades she had brought away from the line and started flipping it around his fingers.
There's something methodical to his movements, as he repeats that motion for all three other knives and the one sword Isabelle brought to him. He pushes one in particular aside with a hum, running a finger over the dull part of the blade.
"Is this a throwing knife?"
Isabelle nods, a little impressed, Leo hums again, and it almost sounds in tune with the song on the radio as though he knows it by heart.
"Are demons resistant to toxins?"
Isabelle leans forward a little, so she can watch him still caressing the small crease that connects the blade with the handle.
"Depends on what you mean by toxin"
Leo nods, throwing the knife upwards and expertly catching it with his other hand, tip pointing to the ceiling.
"This one wants to be poisonous"
Something curls around his words, like he just barely stopped himself from saying it in a different language; it probably wasn't Spanish, he's slipped a few times, so he's aware Isabelle understands him perfectly. It was probably his father's language, Simon told her Leo was very careful to refer to the Greek Parthenon as either 'deities' or 'the Olympians"; something about names having power.
"I can do that"
Leo nods at her, putting the knife down on the table again, close to the others, and then he finally goes for the bracelet that hides Isabelle's whip.
"Now this is more to my speed"
The song on the radio has changed, and the expression in Leo's face has too; Isabelle takes a chance.
"How so?"
Leo smiles, like he's about to tell her something ridiculous.
"Pens, coins, rings; they always turn to swords though"
He twirls the bracelet around so the light from the lightbulb refracts off of it.
"Makes me wonder what you could do with celestial bronze, never mind Imperial Gold, or even Stygian iron"
He smiles sheepishly.
"Not that I've ever worked with Stygian iron, considering only children of Hades can touch the stuff"
Isabelle arches an eyebrow.
"What about the other two?"
Leo gives her an appreciative look, clearly enjoying her enthusiasm over this.
"Imperial Gold is extremely rare, and not somewhere I can go to anymore; celestial bronze would be easier, but I don't know if it would interact with you"
She nods in understanding; it's why she hadn't brought any Nephilim-activated creations other than her whip.
"So, can I see your hammer?"
Leo grins at her, jumping away from his chair in order to dig at his jacket's pocket, pulling out a cube the size of a common die; he moves back a few paces, presses his thumb against one of the differently colored faces, and out pops the Warhammer.
"It's a bit of a mess look-wise, but it resists my fire, so I can't complain"
And Isabelle can tell Leo's used it plenty, so it has clearly fulfilled its role as a weapon, keeping Leo alive and fighting.
"So why a hammer?"
And that gets him going.
