Apparently, Amy may have appeared on this week’s episode of Warehouse 13 — shall attempt to verify this asap!
EDIT: Thanks to Richard for confirming the news! Amy was indeed in the 2×09 Warehouse 13 episode, titled ‘The Ones You Love’ — IMDB has listed Amy’s character as being ‘Tracey’. Screencaptures shall be added shortly.
She was in the episode. She played the main character Myka’s sister.
