Cries! Poor Pops! What was he doing in Switzerland anyway? I was a tad confused with all the extra characters I didn't recognize. Sniffles over Pops.

During the said episode, Zenigata was having hallucinations of Lupin taunting him.

Actually, Zenigata DID almost lost his sanity in one episode after chasing Lupin so much. He kept trying to avoid him, but eventually gave up and went back to chasing Lupin.

Wow. Strange. Good. but Strange.
