He couldn't justify Aphrodite's actions to Fetish. He didn't even know what they had talked about, and he wasn't Aphrodite. He knew deep down inside himself that she wouldn't intentionally hurt him - that over three thousand years of a relationship meant more than a cheap shot at Hades.
But Fetish didn't know that. And Ares couldn't say for sure whether these millennia meant anything to Dite or whether she saw him as... a tool, or whatever.
"I don't feel like she's wronged me before in the past. She's always been there for me, for our children. She's always loved me and I don't think... she doesn't have a reason to lie about these things."
He didn't want to go but he felt like he was being rejected. He couldn't see anything wrong with what he had with Aphrodite - she had been nothing but his angel - and now...
Now it seemed like she was a wedge between this friendship.
He could have said a million things but nothing could salvage this. He felt like nothing could change. He felt like she... was forcing his hand. He couldn't possibly choose anyone over Aphrodite and yet they both... they both meant so much to him.
