As soon as she notices you, her mouth opens wide in a malicious grin. Her mouth opens a bit too wide, though. Before you have time to react, she dashes towards you. As she does so, however, the pillow bursts into a mess of white triangles, which rapidly cover yourself and Becca. As they do, the strange girl seems to grow larger, as does the entire room. Her strike lands somewhere above you. She looks confused at her miss, looks around the room, then walks out into the hallway.
You aren't exactly sure why she left you alone, but you aren't going to complain. It would be nice if you could move, though.
