Most important news from this episode imo was that Rimuru gotta be careful after all. Even if he didn't go all out (although he said he went full power when he created the black flame), these ogres were too dangerous to his comfort zone. Once he names them and they get a proportional power boost like the goblins, they'll be pretty much second only to Veldora. I'm sure even Rimuru is weary about that, because at the end of the episode he was all like 'names ... huh ...', which didn't give the impression that he's all that eager to throw that kind of power up their way.

Also, cutest ogres in fiction. Forget about Shrek.
