In Season 1, Episode 14, Leonard wants to get rid of all his collectibles after an argument with Penny. He says he’ll sell his entire lot to Larry at the comic book store.
I know of Lonely Larry, but it seems unlikely an individual would buy an entire collection, and that the deal will take place in a store.
Instead it seemed like Leonard is selling his stuff to the owner of the store. So is this the same comic book store that Stuart owned? Was the previous owner called Larry? Or did the guys frequent another comic book store in season 1?
