I believe we had a discussion about his once before, circulating around the seemingly surprised look on Michael's and Tom's faces when Geary makes his revelation.
The surprised look is not a response to Geary knowing Michael's plan, IMO. As Geary said, "The LAH-sense will be in Klingman's name." In order for Michael or his representatives to get on the license, or to get Klingman off the license, they'd have to file an application, which is a public process. And, as I've posted before, I believe Turnbull was Geary's political bagman--an intermediary between Geary and the people who need to bribe him to get his political favors.

The logic, IMO, is that Michael knew all this, and had arranged with Turnbull beforehand to bribe Geary through him in order to get on the license. If you accept that, you might conclude that the surprised look is in response not to Geary knowing that Michael was going to move Klingman out (he'd know that through Turnbull or through a public filing), but in response to Geary's saying "That will leave you with a problem..." Why should he have a problem if he'd already paid off through Turnbull? Notice that the first thing Michael says after hearing about his "problem" is, "Turnbull's a good man," which I interpret to mean, "I already took care of you through Turnbull. Why should I have a problem?"
