Pilot - S1-E1

Plot hole: Brian calls Rebecca after he has been shot. She asks him "Where is the bullet? Is it in your leg still?" Brian never mentioned he was shot in the leg. (00:30:20)

Midvale - S3-E6

Plot hole: After Kara and Alex are run off the road, Kara is convinced by "Noel Neill", revealed later to be J'onn, to stop using her powers. From context, J'onn had to have been summoned by Eliza, but in 2007, she would still think he's just Hank Henshaw; she doesn't learn he's not, or even that he's a shapeshifter, until 2016, as seen in season 1's "Myriad", well after Kara and Alex have grown up.
