Tell you a secret: I cheat. I have a local copy of everything I could salvage of the old site from the Wayback Machine, which means I can rapidly flip through entire storylines.

I remembered that Lem had to get Claire’s glasses off to hypnotize her, but wasn’t sure if we’d actually gotten a shot of glasses-less Claire in that scene. But it was simple to check (we did), and then to page back through to her first appearance (which was just in the previous case) to see if there was an earlier instance (there was).
