What's to understand?
I don't understand this one at all, especially since my understanding was that First Global was not terribly efficient.
My guess is that someone (either Glenn or one of the "authorities") told them that they needed to have a transfer agent at all times. (Duh!) Pacific was already plenty pissed off, so they went back to Global, hat in hand.
We don't, of course, know whether they've entirely abandoned the idea of opening their own transfer agency, but one would hope so.
