Susanna Thompson Is Returning For Arrow Episode 100

Add another to the list of guests returning for Arrow Episode 100… one of our guesses turned out to be right!

In addition to Jamey Sheridan (Robert Queen), Katie Cassidy (Laurel Lance), Caity Lotz (Sara), and Deathstroke (who may or may not be Manu Bennett)…. Susanna Thompson (Moira) is making her Arrow return! EW broke the news this evening.

Odd as this is part of a crossover, as one would think that looking back like this would be its own independent thing, right?

Colin Donnell, we know you’re busy with Chicago Med and all but you’d make this episode complete… you too, Colton Haynes. As it stands so far, though…. well played, Arrow writers.

If you can’t wait for Arrow Episode 100 to see Susanna Thompson being awesome, tune in to Timeless on NBC. The first episode airs Monday, October 3 at 10PM… and it’s fantastic.
