One of the best examples of this comes is actor Victor Garber and his character Dr. Martin Stein, who is one half of the combustibles superhero Firestorm. The cast also includes Brandon Routh, Arthur Darvill, Wentworth Miller, Dominic Purcell, Caity Lotz, Franz Drameh, Nick Zano, and Maisie Richardson-Sellers.
"After the defeat of Eobard Thawne and his equally nefarious Legion of Doom, the Legends face a new threat created by their actions at the end of last season". He has appeared as a series regular since the show premiered.
Garber's exit will be a blow to Legends, as Stein often serves as the voice of reason within the group.
However, if Garber does exit the series, it could be a temporary departure. How it will effect the crew as a whole and Jefferson specifically remains to be seen.
Garber plans to make good use of his new free time with a return to Broadway in a revival of Hello, Dolly!
The season 3 premiere of Legends revealed that Stein's daughter Lily was expecting a child. But, with his first grandchild on the way, it would be reasonable to assume that Stein decides to leave his superhero days behind him to spend time with his growing family.
What will this mean for Firestorm?
The next episode of Legends of Tomorrow will air on Tuesday, October 17 on The CW.
