It is curious in a way, but then again I felt like up until the finale Henry didn't have all that much screentime this season either. Maybe it's only a subjective impression, though, I don't have the stats in mind right now, but I kept thinking all year that he'd been a bit... sidelined.
I still think it would have been nice if they'd found a way to include Roland in that diner scene in 4x22 to give them at least one brief moment together in 4b, but alas... here's hoping for more Roland and Henry next season.
