Arrowverse Crossover: 11 Best Moments From Arrow's 100th Episode 'Invasion!'
9. The Queen Family
Arrow was, as you'd expect from the 100th episode of a comic book TV show, heavy on the fan service. A big part of that was from the returning cast, and few were more welcome than the Queens. (Okay, mostly Moira.)
It was great to see both Jamey Sheridan and Susanna Thompson reprise their roles: a reminder of how wonderful a character the Queen family matriarch was, and how much of an impact their deaths had on Oliver and Thea.
Seeing the Queen family all together was a lovely touch, and their presence served as a nice callback and helped bring the emotional weight the episode required.
