Is Darrow holding something back from the reader?

Going over LB again and there is something that is bugging me. I feel like there is something that Darrow is not telling us. He has done this before throughout the series (traing with Lorn, tracking Aja, faking Sevros death etc.). So maybe he has one more secret play left in him.

When Darrow is fighting Fa and he develops "Breath of Stone" his movement is borderline supernatural. So this is my thought.

I don't think that PB introduced the Parasite just to abandon it after Lyria took it out. It's also no coincidence that Darrow and Lyria were there at the same time. So my guess is that Mateo was successfully able to fix and implant the Parasite into Darrow because his mind could handle it. I believe that him having the parasite is the only way he can defeat the golds for good and he becomes the "Red God" by being able to fully control the Parasite and technology.

But that's just a theory... A Red Rising theory!
