She had noticed what had happened and saw that cresent got hurt pretty bad, the door was unlocked and the monster is distracted, so she ran as fast as she could to cresent picked him up and ran to the door hoping that the monster doesn't fallow them, but unfortunately it did, so she was trying to open and close the door as fast as possible then started running down the hall, hoping that the door would distract the monster long enough for them to escape.
