That 'blue light' was reg imaging 'what if I had hit Riko' with the incinerator. His nightmare was just a mixture of his worst fears of what could have happened.
Fun fact the next few episodes are technically filler (but not really), its what the author originally planned to draw but could not draw due to constraints The manga at this time was doing really bad and the publisers were going to pull the plug because it was not making money So the author speed ran getting to a major story moment in only about 3 chapters and it worked and this manga became the largest IP for the publisher by the skin of its teeth and im happy it worked because this is my favorite fantasy setting ever
@@YanceyX223 Yeah, this comment was a bit ahead of itself. The 3rd layer episode was 'filler' which I don't think its really truly filler, just most of it wasn't in the manga. And the episode where they did survival training was basically less then a single page in the manga, which they extended in the anime. That said, I think its true that he was pressured around this time to bring in Ozen to drop some more plot based stuff instead of the more slow burn world-building/atmospheric storytelling he had been doing. But I don't think there was really the real threat of the manga being dropped until after the Ozen arc, which is why the 3rd layer was speedrun in the manga to get to what what ended up being episode 10's content, to increase the stakes, introduce new characters and make it more 'exciting'. If I recall right he had a rough draft of a lot of stuff after the Ozen arc they he ended up scrapping a lot of based on feedback from either an editor or the publisher, which is largely why it ended up the way that it did in the second half of this season.
This is the point it really starts to let you know "we were not joking or exaggerating" about all the things that were warned about the Abyss up to this point. Every delver dies down here eventually, one way or another. Firing the Incinerator here was an absolutely gorgeous two-page spread in the manga. It looks great in the anime as well, but it can't really do the original justice. "how much energy you need for it" When they charged Reg up at the beginning of the series, it wasn't just the orphanage that lost power, it turns out it was the _entire district._ The "eggs" are relics called Sun Spheres. They light up. In the manga, Riko had one from the very start (one of the things she stole for herself instead of handing in) but since they cut that out from the anime they had to add her finding one here to establish she has it.
Good video. Just wanted to mention that occasionally at the beginning or ending of an episode you will hear a voice providing narration, and that most people would probably say this is Lyza, Riko's mom. Though, caution: season 2 has a completely different narrator, and it will be clear who that is at that time.
