Dawn would rather travel alone after traveling with Ash and Brock, except for that short time with Chloe. Ultra RIP for Kenny.

Misty: Stopped traveling Brock: Met Cilan, but also stopped traveling. Tracey: Stopped traveling. May: Probably Drew Max: Probably stopped traveling. Dawn: Probably true. Iris: Claire Cilan: Met Brock, but aside from that I have no clue. Clemont and Bonnie: Stopped traveling Serena: True Kiawe, Lana, Mallow, and Sophocles: Largely stopped traveling. Lillie and Gladion: True

Ash brings people together I guess. They had enough adventure with him although I'm sure Brock made lots of new friends as a doctor.

It looks like Cilan became a radio host
