The Kristen Kramer of the comics worked alongside Barry Allen in the crime lab, and this prosecutor just arrived from Gotham with a mostly redacted military past.
Unfortunately, it’s hard to say whether Kristen Kramer will be a friend or foe to Team Flash, as The Flash took some liberties with its iteration of the character.
For now, Kramer isn’t directly on the path of Killer Frost, as Joe and Iris seemed committed to run interference and keep her off their friend’s back.
