I probably should've done this review a long time ago, but I hope that this will suffice:
Seriously, Olivia? Could she possibly be any less mature? Wait, never mind, she probably could, which is pretty scary to think about. The way she's treating Oshawott leads me to believe that future neglect is more of a "when" than an "if". Sooner or later, Oshawott is going to realize that Olivia isn't the same way with him as she is with Roselia and Minccino. When that happens, it's going to create a huge amount of resentment and/or guilt on Oshawott's part - both of which could badly stunt his emotional growth. If the three adults have any sense whatsoever, they should put their foot down right now before it has a chance to get to that point.
Look at Ash's Charizard when it evolved. Then think of the worst-case scenario of an emotionally-underdeveloped Dewott/Samurott in their midst. You'll understand my concerns.
Doughnuts and whiskey?! Ariana is awesome. Enough said. And thank fate that the trio stopped using that awful motto. You'd think that it would've gotten stale after all the episodes they used it in...
Renzo...I see that he's just as batshit insane and obsessed as ever. The guy really does have problems (if one could dismiss whatever raging insanity he has as merely a problem). Hell, it wouldn't surprise me if he turned to stalking them because of his fixating behavior, but it also wouldn't surprise me if he knew more details than he should about Rich's death.
It worries me what his motives are, but what he might do after he completes his goal worries me even more. Renzo does not seem like the type to move on. It's a scary thought, but I think that even if he does manage to reveal whatever he thinks is the truth about Rich, he'll still stalk and harass his family and friends, not to gloat about his victory, but because he simply doesn't know how to do anything else.
The first thing I noticed about the Sacred Helix was that Archer had joined them. One of two options popped into my head: either he's upset at Giovanni for taking back control or he's there to spy on the Sacred Helix for TR. Either way, I love how you portrayed him: calm and completely in control of his surroundings. He's probably the only character I truly like out of that entire group. Still, I thought that Archer had blue hair...
Geminus is a very interesting name to take. In Ancient Greek history, Geminus was one of the forefathers of mathematics and astronomy. Not many people would've thought of him before such names like Plato or Aristotle. I'm impressed.
As for this story's Geminus...I have all sorts of theories about him, but if any of them are close to being right...well, he could very well be the most powerful person in that room. And now I'm hearing legends being referred to as "angels".
Now I don't just hate Polaris beyond all reason. I'm also extremely frightened about what they might be capable of if they had one of those legends in their grasp... Fate, just imagine a terrorist cult going for total control of a whole group of monsters that are on a god-like level. They're already more scary than any villain I've seen in your fics - which I had thought impossible. Major, major kudos to you for establishing that in the second chapter of your story.
Overall, I don't think you could've played it out better than you did. Even Olivia's brattiness looked like it had a place in the chapter. This was excellently done. I'm excited to see what the next chapter will hold, whenever it comes out.
