Grimm Season Finale

I opened a small Etsy shop in December 2012.  Until recently, it contained these two purple bottles.  About a month ago I sold them to a gentleman from NBC Studios.  He said if they were approved, they'd appear in the season finale of Grimm.  Of course I had to start watching the show, and now I'm hooked.

The season finale is Tuesday, May 21 - 9 pm Central Time.  Can't wait to see how they defeat the zombie army with (hopefully) the aid of my little bottles!  :)
