That blows Zack's mind. Seven billion years being what he is... the idea of something different is gobsmacking. Of course he wants a change though, isn't that what making friends with Alec and seeing new places was all about? He'll just rub his head because it hurts again. Quite a lot.

Which supports what Alec is saying.

The idea of existing outside of linear time is a weird concept too. Zack thinks it must be amazing to be Alec, despite all the shitty aspects.

"Could we... you..." Gaia's arse, Alec has given him so much already. He hates to ask, but, "would you help me get rid of it?" It's scary. No, it's fucking terrifying, the thought of magic and change, but to lose the pain would make such a difference to Zack's existence.
