Piper Halliwell's Realtor

Piper's realtor was a blonde woman who Piper hired to find her the right place for her restaurant.

Finding a place for Piper's restaurant
This blonde woman had taken Piper to eight different places to see if she could start her restaurant there. The last place had Piper convinced, though her realtor found it a dump.

Because of a spell that the Source of All Evil had cast on all mortals of the mortal world, the realtor suddenly turned demonic and began to attack Piper. After a while, Piper could freeze the realtor and escape, driving back to the manor.

It is unknown what has happened with her afterwards, although it may be presumed that she turned back to normal when she unfroze.
