Mayfair Witches S02E02 - Ten of Swords

Mayfair Witches S02 E02 AMC Networks

From IMDb: Rowan must find Lasher before more people are hurt; Sip finds an ally in an angry Mayfair cousin.

I watched the entire episode thinking the actress playing Gifford was one I recognized from...somewhere...but didn't realize it was Thora Birch until I went to look for some meaningful images from the episode.  Wow.  She made a good Gifford Mayfair!
