Well, for my system, Kiya is the oldest and body age. So, with important people who need to know (like T or in group T) I tell them that if they need "an adult" in the system, or I've switched into someone that isn't helpful, to ask for Kiya. And to get Kiya back, they actually have to talk about things Kiya knows about (jokes/ humor is good too). Hope that might help some.... Find out who in your system is the one that holds things together or is the older one - who ever it is you want to have the main system in control... and give your H that info and how to access that one.
