Gaius really was bewildered by this world. The supernatural was real here, and even though he had found his faith, it was still a difficult thing to grasp. God and angels were one thing. He could even believe in demons, given that most things usually did have some kind of darker reflection. Magic, reality warping pranksters, and "fictional people" on the other hand? Those were things he was still having trouble wrapping his mind around. He had faith now, but all his life, he'd been a man of science. Some things were still just difficult for him.
One thing that had changed? His ability to deny reality and live in his own little world. Despite how much he desperately wanted to believe this was all some dream, or maybe some mad hallucination, he had empirical proof that despite how unreal these phenomena seemed, they were happening. He'd seen these things with his own eyes, and while each was different, the reality of them was repeated each time. It may not have been quite the scientific method he was used to, but it was good enough for him.
Which left him in a somewhat awkward position. He'd been brave and selfless once, yes. It had felt good, yes. Caprica being proud of him afterward had felt very good, yes. But with this new selflessnes came a surprising self-doubt. He'd never been truly selfless. He carried the weight of millions of lives on his shoulders simply because he was too selfish to give up a pretty blonde or take on a little more work. How could he be sure he'd be able to do it again? Especially with the odds they were facing. How could he be sure he'd be strong enough, when the time came?
Still. One thing Gaius had learned was to worry about one thing at a time. "That sounds like a wonderful idea, I'm glad I thought of it," he teased, smirking slightly. "I know a few things, yes." Of course, there was the question of just how much technology they wanted to allow in their home. But they would cross that bridge when they came to it.
