Kiari hears her door start to open, assumes that it's her sister or brother coming in, but recoils, or as close to it as she can at her size, when she sees someone who isn't either of them. She tries to cover herself up with a blanket to hide her size, but the blanket, at this point, has no hope of covering her, and even if it did, it wouldn't really be very effective at hiding much W-who's there?
