Yeah, I also noticed that most of the player trainers are just in and out with the lab. I'm thinking after his conversation with Elm, Kiba will call all of the trainers' numbers at once, instructing them to meet at Violet City somewhere, that way the characters actually know what they're doing and why they're on this quest.
Hey there, hope youre well!
Just put up my second Seren post, let me know what you think and also PM about what's next if you've got time :p
I'll be busy again until weds, but I should be able to pop on now and then during work.
