Princess Celestia was having a normal morning reading by the fire, or she was until her friend and former pupil had randomly teleported into her room without warning to pay her a visit.
The royal goddess of the sun soon figured out that her visitor was intoxicated and would now have to babysit her and make sure she was safe until she sobered up enough to go home without further incident.

Unfortunately for Celestia, it all goes very wrong very quickly.
