Honestly, Zelos' first instinct is to run away from the source of this mess, every single self-preservation alarm in his mind and core screaming 'save yourself save yourself save yourself' within the cacophony of calculations and his systems trying to stabilize in the situation. He pulls at Sheena, urging her in literally any direction except south, still coughing up the remains of that lump in his throat. The ether in the area tastes like raw emotion, bitter and scalding with its rage. Much like his own has before, back when he was in--

Zelos abruptly stops thinking about that for long enough to hear Kratos mention Mithos' name.

And it's--it's like a bucket of cold water is dumped on him, a half-guilty, half-horrified feeling sinking to the bottom of his core like a fishing line that hooks down and pulls him south. Mithos. An Aegis. He's causing this. A blade is suffering. An Aegis is suffering. An original is suffering. And Zelos, he's--here he is, thinking of running away and saving himself like a coward while Kratos puts himself at risk for Mithos, while someone with an actual place in this world suffers for--

It's not going to continue.

Zelos draws in a sharp breath and abruptly lets go of Sheena's arm. He gets up to his full-height and doesn't think about it when he starts walking south, refuses to, just focuses on Kratos' retreating back. That hook in his core pulls him forward and he lets it, ignoring everything else in favour of making himself useful by helping Tethe'alla's rightful Aegis.

It's the least he can do with his miserable existence, right?
