Zagreus dodges, and he's back on Theseus. He will deal with how attractive that was at a later point, when he is not currently in a battle to the death.

Hey, water conducts electricity, maybe if he gets Theseus wet he can make the hero electrify himself. Or he could just deflect his spear back, one of those.

Or all of those.

Water does not turn out to cause Theseus to electrify himself, possibly because it's divine bullshit, or possibly because there's just not enough of it present to manage it. Deflecting his spear back definitely works, though. Yvette is very dutiful about giving him a heads up for lightning blasts, and drags Theseus into blade whirlwinds, trips him up, and occasionally sunblasts him, when there's an opening available.

Unfortunately for Zagreus, Theseus is a very skilled and practiced fighter, and Zagreus got to fight his way through all of Tartarus, Asphodel, and Elysium to get here, and a minotaur besides. Theseus also has more reach, and a shield, and the ability to lunge forward with this really irritating sweeping strike that is a bit of a bitch to dodge, and, well. At one point, Zagreus is stabbed. Mortally.

"Zag—!" hisses Yvette, a half second too late.

"Fuck!" he says, looking at the hole in his chest. "I wanted to save that for later," he growls, and a swirl of darkness emerges from within his body, pulling him up into the air and then exploding outwards in a shockwave. When he lands back on his feet, the wound is healed, and though he still looks beat up he very much does not look dead.

"... Wait, what?"

"Too bad, blackguard. I will slay you again, and again, and again, until you finally fall for good and return to the pits of Tartarus where you belong!"

And then it's back to fighting! Theseus does not really seem surprised by Zagreus's ability to defy death itself.

It would be bad tactics to let something like that create an opening and whatever his faults Theseus is one of the greatest warriors Greece has ever seen.

Nevertheless, Zagreus is a god, was taught by Achilles himself, and is really fucking pissed off. Yes, Tartarus and Asphodel and Elysium and that damn bull have taken their toll, but their toll is not enough to stop him. Not now, not here.

"You're dead," he says a split second before the blow he lands past Theseus's defense buries his sword in the hero's gut.

"Khh, why, you..."

And then, just like that, he fades away.

Zagreus spends a few seconds there, motionless, breathing heavily, before standing straight and letting out one deep breath.

It seems the crowd is cheering.

They seem to be chanting "ZA-GRE-US! ZA-GRE-US!"

Well.

That's unexpected.

Not entirely unwelcome, though. He grins and extends his arms up and to the sides, then bows to his audience.

"Hey, to your left. You have a fan," murmurs Yvette, amused and relieved.

And, yep, right over there, amidst a sea of blue banners with Theseus and Asterius's faces stamped on them, is a little orange banner with Zagreus's face. The shade just above it is in orange, and looks thrilled to pieces.

...oh.

He hops on over to that shade and beams up at them.

This is the GREATEST MOMENT OF THIS SHADE'S NOT-QUITE-LIFE-ANYMORE and they are SO THRILLED!!!!! SO THRILLED!!! AAAA!!!!

He bows again, this time directly to that shade, and says, "Hope you'll come cheer next time! Thanks for your support!"

AAAAAA they are being DIRECTLY ADDRESSED this day cannot get any BETTER, this is it, this is the perfect day, aaaaaa so exciting aaaaaa!

Yvette lets out a little giggle. This is very cute.

And onwards to... well, whatever comes after this. He hasn't been this far before.

Well, first, once they are out of the coliseum and in the next little waystation room, Yvette remakes her construct so she can hug him!

"Sorry, I realize I didn't get a chance to warn you about my trap for Theseus, that was probably kind of scary? I'm fine."

Hug! "Oh, no, I have seen what you can do in the previous chambers, I knew you were fine."

"Oh! Okay, good. Well, I'm glad you survived your stabbing, too."

"Yeah, uh, about that. I didn't, not quite."

"... Oh?"

"I figured out how to—cheat, sort of. A while ago. Erm, I don't really know how to explain how it works. I was taking some of Styx, with me, and now I don't have it anymore, it's returned. Next time I die will be for real."

"Oh. Damn. Okay. Uh. I guess I'll start working on some way to protect you? What's ahead to worry about?"

"No clue! First time I've gotten this far."

"... Great! Okay. Do you have an estimation for how close we are to the surface?"
