Stun gun wristwatch

I'd love to bring back Samizu Kichiemon. love his mechanical traps. especially his Warehouse from Battle of the Haunted warehouse's treasure it blew my mind.

I guess i missed that one. thanks...

I am watching DC for a while now. I have watched almost all episodes (not OVA's). but in episode #827, in the ramen to die for shop, conan mentions about the child living in here hotel room in the following way, "Are you sure it's not for the person living in your hotel room?" with the child's ( the one living in Masumi's hotel room) photo in the background. I have not seen any episode where conan saw her. Have i missed the episode? please tell me the episode number if so. Thank You
