All's Wells That Ends Wells - S7-E1
Continuity mistake: Iris is backing up away from her evil counterpart while holding her hands up in front of her. She has fake white nails on, but in the next shot with evil Iris in front view, it shows her hands and there are no fake nails and no nail polish. These are the hands of a stunt double backing up. (00:21:28)
Continuity mistake: When Iris is showing Frost's mother the obituary, in a shot facing the mother she's holding the folder open, then after she says "it feels cold", the shot changes to behind her and the folder is instantly shut.
The Man in the Yellow Tie - S8-E18
Continuity mistake: At the start when Flash is struck by the accidental lightning, he rolls on the ground and gets mud on his back. When he stands up, and we see his back in a reverse shot, there's no mud.
