Midvale - S3-E6 Corrected entry: Teenage Kara has pierced ears, even though her skin is supposed to be impenetrable. (00:13:15) Cubs Fan ★
Correction: Magnetic clip-on earrings exist, and can make the sort of dents in her ears which these seem to, due to the strength of magnet involved. Adult Kara also has the same earrings, as seen in the "previously on..." segment.
