lol I didn't actually rewatch very much (except for S5 where I kept getting distracted by the show being AWESOME), I just skipped through the episodes; the stained glass really pops so if it's obvious in a scene it's usually easy to catch. I'm sure I missed a bunch, but the first four seasons it wasn't that hard since it was mostly just skipping through to find the mansion scenes.

I MISS LANA SO MUCH. I WATCHED THE EPISODE WHERE SHE WAS A FRENCH KRYPTONIAN WITCH IN CHINA FOR THE FIRST TIME LAST WEEK AND OMG I ALMOST HURT SOMETHING LAUGHING AT THE BAD WIRE WORK. COME BACK, LANA.
