Whether or not the goddess agreed wasn't enough, and she never did tell him now did she? No, she must've made a mistake, that was the only explanation as to why he hadn't fit in the world he was made. He just didn't have that same faith as Phoebe, that the gods were so sure. If they were human enough to war, they were human enough to err.
"I guess," was his simple and avoidant response, because he didn't want to pry further into the validity of gods.
After Killian's whole bit about how he felt, and how it was a lost cause anyway, there was a moment of silence. Killian looked down, eyebrows furrowed with frustration and hoping he hadn't said anything to offend Phoebe. He just didn't know what he was doing, he was indeed lost. But then she spoke up again, and what she said seemed to fit perfectly. Somehow she'd pulled the truth out of all his mixed up feelings, and to be understood felt like a small weight had been lifted from his broad shoulders.
He nodded, still looking down. "Especially when I couldn't even do that one thing right. I had one job Phoebe, and every chance I got I made the wrong decision. Sometimes I think I just wanted to prove to them what I always thought, that I wasn't good enough. I don't know, it's just like, if I couldn't be right when all the rules were laid out for me, how am I supposed to figure out what I'm doing when I have absolutely nothing to go on? I wanted to have all this freedom, and it feels great, but I don't want to waste it."
