I'm thinking SiTe for Branson. He seems to have Si blinking and scowl as his default. He does a little more Se like eye toggling than I would expect, and they have a bit of the Se sparkle, but I think his Si cues trump that. On the rare occasions he used his hands he had the characteristic Te closed fingered with the Fi curves on the ends. He had a few blunt Te brow raises as well as a giddy Fi laugh. Because of his Pi viscous body swaying and eyes drifting to the sides I put Si before Te.
Edit: Branson also has that characteristic Te/Fi smile, where it is big and wide like an Fe smile except it's lacking the Fe warmth. Instead it has a slight awkwardness to it, like he's wincing.
