Question about the ending (spoilers)
Why does Steven put the key back on Emily's keychain at the end when he thinks she's gone out to get them something to eat? She had just told him she still can't find her key and thinks they should have the locks changed and then he puts the right key back on her keychain when he thinks she's not looking?! What would she say/think when all of a sudden the right key is back on her keychain? That was stupid on his part.
