Even though the chapters are separate moments from their relationship, I hope that we get to read about the dinner at the Petrelli's.
I think it's good that you've brought in some more drama, because I think it makes their relationship more real, and because I like to see how they overcome their obsticles.
I didn't know how to review the whole story (is that even possible?), so I commented the first chapter but I have read all chapters so far. (1-5)
I like it! Really good, I love Isaac and Peter isn't all that bad either, so love the idea of a relationship between them ;)
And I also think you nailed the part where Nathan came in and started lecturing them about their relationship, I think it's exactly what would of happened!
The only negative thing I have to say is that it's a bit too happy and romantic. Maybe a chapter about Isaac slipping and them fighting about it, only to later on make their relationship stronger? I mean, every couple have problems, and their way of dealing with it would be great to read about :)
