Felix is the one who gets wounded at the construction site fight and he’s the one who gets blinded by Locus’ flash bang in the night club despite Locus calling it out that he’s about to throw it. I love Felix but I think that Locus was always the more competent one and Felix knew it but he’d never admit it.
This particular series is in season 14 of Red vs Blue. It's the past for the characters Locus and Felix, telling you that they weren't always villains. There are reuploads on RU-vid as the company who made the series no longer exists
