Relic Castle

Hello, I'm not necessarily having any bug issues, but rather that I just don't know what to do here, and I have a couple of questions.

Is it possible to set route on your partner trainers during events?
How do I keep the partner trainer from disappearing when splitting up with them to go back to town?

I know how to set up partner trainers, their dialogue, Pokemon, etc, but I don't know how to make them move away from the player after splitting up rather than them disappearing (or how to stop them from disappearing), nor do I know how to set their route for an event that they're a part of.


The event for the partner trainer, and the event for removing them to go back to town is in the link.

Any help on this issue is very much appreciated.
