What chapter when Yuuri met Conrad again after he left Yuuri? (I mean RAW scan)

If you're talking about when they meet in the arena of the tournament in Big Shimaron, chapter 87. If you're talking about the novels (when Yuuri sees Conrad again in Small Shimaron while he's having his meeting with Saralegui), then that doesn't happen in the manga. Yuuri and the rest haven't left Big Shimaron yet (after the tournament the story was changed in the manga and they're still there).
