Diana didn't have to watch for long. Thor went for the kill, bringing Stormbreaker down towards Ares' head. He wasn't about to make the same mistakes again. The blow was fast, a blur of silver and wood moving through the dark with light around it. Ares pivoted and in the moment that followed, the light went out.
Thor fell with his own weapon buried in his chest. Ares had turned the blow and made sure Thor wasn't getting up from that one. The ambient electricity faded from the weapon and from Thor's eyes, then Ares turned back to Diana.
