Special guest Donny Osmond supported the appearance of Dani Daortiz. 

"Knight & Gayle" and "Jonah Babins & Ben Train" are each two-person magic teams. 

TVDB, my cable guide, and this episode summary all listed these magicians as performing in this episode: Blaise Serra, Pierre Ulric, Francis Menotti, and Lord of the Ring. 

But, magicians Blaise Serra, Leon Etienne, Xavier Mortimer, and Sylvain Juzan actually performed. I watched it last night and updated the summary. Anyone can verify this at The CW's website by viewing "Jaws of Death" here: https://www.cwtv.com/shows/penn-teller-fool-us/. Also, Leon Etienne used a Jaws-of-Death device in his performance, hence the name of this episode.

Pierre Ulric and Francis Menotti performed in "Lord Of The Ring" last week on October 19, 2020.

I think most of Alyson's reactions to the one magician that used the more gory magic techniques was mostly good acting. She had to have seen a lot more gross makeup on people when she was playing Willow on Buffy the Vampire Slayer than what the one magician presented on the stage so kudos to her for such a good job.
