An appeal to Shinji.
What makes a place feel like home? Is it warmth and familiarity? Some idealized, make-believe TV-version of the American dream? Is it love and acceptance? Or is it simple safety? Or it's none of those things. And it's a place where the captain of the football team is murdered. Or maybe it's just a forgotten closet under a well-trod staircase, where it's just you and the mice and the spiders, like an extra in a Wes Craven movie.
— You see, Vincent... you're the missing part of my life. And I'm the missing part of your life. When we find mama... We can fill the missing part of hers. We won't be alone any more. We can be a family.
— A family? You mean, like, with a Christmas tree... and Thanksgiving dinner?
— And a real home... where you'll always be welcome.
— Always?
— Even when you've been bad.
