Cyrus is one of four characters to have Flurry of Blows as their Adrenaline rush, the others being Allen, Jody and John.
Cyrus appears as an ally in the Larger World #1 (Act 1, Stage 6 and Act 2, Stage 2, Stage 3 and Stage 8) Roadmap mission.
It's highly possible that Cyrus and Timothy are Saviors; this is supported by the fact that in the storyline of the Larger World #1 Roadmap mission, a group of Saviors are killing walkers near the Hilltop, because of the deal between the communities. When playing this mission, Cyrus appears as an ally multiple times, indicating that he could be most likely a Savior.
