Finding Grusha on Glaseado Mountain isn't surprising. Despite his complaints about the cold, it's a place he's spent most of his life in. He's used to the snowy weather. Plus Cetoddle prefers the cold climate too.
With no aspiring young trainers around to take on his gym, he has to find something to do. Normally it's training his Pokemon or exploring the mountain just in case he finds a lost trainer. Today, he's doing neither of those things.
While he is at his gym, he isn't there for battle. His Rotom Phone is out and Cetoddle is curiously peering over at it. Most would assume it's a phone call or something important, but if you listen closely, you can hear Iono. It's not a one-sided call, although it could seem like it, but upon closer inspection he's watching one of her streams.
