I thought he seemed weirdly unaffected during the trial. The first sign that he was even remotely concerned was when he was watching the drone video that shows him provoking the crowd. But reality seemed to hit him hard during the state's closing argument. He was seriously affected by the narrative that actually matches video evidence. His defense team also seems to have all the sudden had reality hit them as hard during the state's closing argument. So much so, I think it seriously threw their own closing off.
Two full days of deliberations seems quite a bit given how strong we now know the evidence to be. The longer the jury is out, the better it may be for him. But he's definitely scared since the day of closing arguments.
