In the future, Tracy Brand will be a highly-regarded and well-celebrated genius. When she arrives on "The Flash," however, she won't be that person quite yet. The site describes her as a "smorgasbord of quirky idiosyncrasies." Somehow, she'll discover her own future legacy and connect with Team Flash.

Dudek is most notably known for her turn on "House" as Doctor Amber Volakis; she also played Piper Perabo's sister on "Covert Affairs" and appeared on numerous episodes of both "Mad Men" and "The Magicians." Her late addition to Season 3 could mean she'll have a more significant role to play in Season 4. Fans already know Season 4 will not have a speedster villain, perhaps her character will connect to Season 4's mystery villain.
