Meda was taking a walk and found herself near the portraits. There were so many portraits she enjoyed stopping to speak with, but today she wasn't looking for any particular framed person and decided to just go an check on all of them.

As she headed down she noticed a few that looked as if they weren't as level as they normally were and looking around she saw a few cracks in the wall above those frames. "Oh dear that isn't good."

It was probably a good reason why those two frames were empty at the time. The poor occupants probably went to find more level ground.
