I'm looking down there, and he isn't there. He was there until I gave him his own job application, and then he disappeared, presumably to go there, but he's not at the Silph Co. building (there's like one guy there who give you the application and no one else) and the Department Store, since I figured that might be affiliated with Silph, but he's not there either. I checked the whole of 7th, and he's not there too.
