A couple notes:
1) The door wasn't and isn't locked or else the woman who is fussing with Drevo wouldn't have been able to get in.
2) So, since that woman came in (in Cuddles' post), the door isn't closed either (meaning that you would more than likely knock on the door frame and not the door, if you knocked at all).
3) Just in case there's any confusion...Kiana is sitting in a chair. There is a different woman fussing with Drevo.
