Four words don't really indicate anything about a character. We could talk about how "As you wish" is something Darth Vader says to Grand Moff Tarkin in the original "Star Wars," but that doesn't signify much. As an inquisitor, Marrok would have been at least partially trained by Vader. Maybe that classical Sith speech pattern just wore off on him. Some fans have also claimed that Marrok's voice sounds similar to that of Starkiller from the "Force Unleashed" video games, played by longtime Darth Maul voice actor Sam Witwer.
What might be more interesting here is that Marrok seems totally deferential to Shin Hati, who herself is Baylan Skoll's apprentice. That places him last in the chain of command that the three have. And of course, unlike the two of them, Marrok actually has a red lightsaber, meaning that he's bled a kyber crystal and is fully committed to the dark side — or so it seems.
Theories will surely continue to fly about who he really is. Could Marrok be a brainwashed Ezra Bridger? A new, canon version of Starkiller? Or maybe just a random inquisitor who managed to survive the fall of the Empire? His helmet and armor resemble other inquisitors, particularly the Eighth Brother from "Star Wars Rebels," who also dies in that show. However, the design is a bit more medieval, suggesting that Marrok may have made some personal modifications after the war. For now, the former inquisitor remains one of the big mysteries of "Ahsoka."
