When we left Sam Alexander last episode, he was claimed by a red ring, reducing him to a mindless rage-zombie capable of nothing but angry noises and spewing flaming blood at the people he once called friends.

Yeah, he didn't get better.

Even as chaotic as the battlefield is, finding him is easier than one might expect - largely because the path of destruction he's cutting is indiscriminate, and he's just as likely to take out yellows as the greens and their allies, truce be damned.
