Katee Sackhoff might be appearing on The Flash in season 4.
Assuming the clues are correct and Sackhoff is headed to Central City, nothing is known at this time as to who she might be playing.
And now it is possible that genre favorite Katee Sackhoff will also make an appearance on the show, though at this time it is not actually known for sure.
For now, though, all we can do is guess. The Flash returns to The CW on Tuesday, October 10.
