The Louvre was just too famous. Jimmy, while on Peter's team reviewing the data, had seen countless references to the Louvre, various artifacts, and original paintings, most of which involved the Louvre's collection. Jimmy wasn't so greedy, though; the Louvre was too vast. He merely visited the painting and Eastern art galleries before leaving the Louvre.
It wasn't that Jimmy was short on time or had pressing tasks, rather while wandering the galleries, he realized he seemed to lack any artistic flair. He had wanted to see if he could cultivate some, to refine his sentiments, but found he was fine with the paintings. When it came to art sculptures and ancient artifacts, he felt nothing, couldn't remember the introductions or names, and forgot everything once he saw it. After two galleries, he gave up, concluding he was not fated for art, and there was no relation to Peter's team after all.
