So basically, one member of your system wants to leave and join another system?

This is just from personal experence, so take it for what it is...

But when members of my system go to the other system, I feel a whole, like when you lose a tooth. There's also a "rubber band" effect. The longer they stay over there, the tigher the rubber band gets, until they feel like they're going to be snapped back.

Now I'm not saying that would happen with everyone, just that's my personal experience.

Hope that helps.
