Does Clu control Rinzler? Or how is their relationship meant to be interpreted, given his transformation later?
Horowitz: [Clu] repurposed Tron into Rinzler, and that's the key difference between Clu and Kevin Flynn - Kevin Flynn could create, Clu could repurpose. All Clu can do is destroy or repurpose, and what he did with Rinzler was, he took Tron and repurposed him. Can he completely control him? No. But I think the idea for us was that the way we wanted to play it is he forgot who he was. It's almost like amnesia. But there was a core to his programming so deep that when he first sees the blood trickle and he says, "User," that's like the first step of like that really core program reawakening.
Kitsis: But when he gets face-to-face with Kevin Flynn is when it slowly starts to come back. So because Kevin was off the Grid and he was hiding for so many cycles, as we say, he never had the opportunity.
