It looks like Thea has got her own villain, which can only be a good thing for her character. Machin doesn't want to hurt her, he wants to thank her for burning his face off because it opened his eyes to the world and what he needs to do. That doesn't stop the pair from fighting it out during this episode, and it's left open for this personal battle to be resumed later down the line. As long as he isn't killed by Darhk, there's definitely scope for Speedy v Anarky III, and bringing the pair into conflict as a recurring part of the series could be a fun way to go.
