I've seen a few reviews asking this question. I don't think they understand that Clementine is a child. There is a reason we don't know exactly what's going on in the house. It's quite obvious that grown-ups wouldn't share that kind of information with a child, especially a child they just met.
In season one we were Lee, a fully grown man who had a strong opinion. That made people turn to him, he were the "natural leader" Therefor we got to know where the main plot is going quite fast, we were creating it.
When being Clementine we need to understand that we can't create the story the same way like we could with Lee. We are just a child, and adults would never trust or seek advice from a child. (Not when there is such a important thing like surviving a zombie apocalypse.)
I don't know what you guys think, but I think the reviewers who are expecting every puzzlebit in the first episode are a bit silly.
That's about it. :)
I hope you guys enjoyed the first episode as much as I did.
