Here's your review, buddy!
Grammar: Again, not really a problem here. I'm starting to think that there must've been a serious problem on Wattpad, or something, because normally by now, I would have come across something. I'm pretty sure even I have a mistake or two, but I'm not seeing anything here. throws brownie points
Characterization: (First of all, your MC has the same name as my first cat, so you already have my admiration)
I mean, there might be something here, as this is in the middle of the story, but I'm not getting much of anything really strong here. They act like characters that you're supposed to root for (the Loyal One, the Courageous One, etc), but not necessarily characters themselves. Archetypes, not necessarily cliche's, but also not where they feel like a real person. For example, when they're attacked by imps, the logical reaction would be to run away, as what Lika'so tells Alex to do. But then he turns around and goes back to fight a moment later. That would make sense if it was already established that his character is self-sacrificing or foolishly headstrong, but there isn't an explanation as to why besides "I want to help my friends!" As the MC, the audience already expects for him to be loyal, that's what makes them the hero, because they're not after their own personal gains. But you also need to tell us why that's so. At this point in the battle, Alex is severely wounded, maybe even mortally so, and not only are they pretty much overpowered, but he also has no weapons whatsoever. How does he intend on defending himself, his friends? What about his wound? How does he feel putting not only his safety on the line, but also that of his friends, who just told him to run away? The reader needs to sit and experience that inner monologue that Alex might undergo, as it reveals his true character and helps in his journey of self-discovery.
Overall Plot: I thought that something felt really familiar about the story while I was reading it, but not in a, "Hey, I've read a story like this before!"-way. It was more like deja vu, and it wasn't until I was reading a little bit longer when I realized why. There's a lot of telling over showing here, and when I started out writing and for a long while after that, I did a lot of it. Like, a lot. It got so bad that I didn't write my story three years, because I didn't know how to fix it and I had gotten frustrated. But then I read some online tips that's shown me the difference between the two and it's greatly helped. Now, that doesn't mean that telling versus showing completely ruins a story, and I still have my moments. All it means is that there needs to be a balance between them. Explaining things to the audience, or "telling", greatly helps when it's meant to speed up scenes that are naturally slow, such as slow dialogue scenes. However, showing should be done when there's a lot of action, such as a battle scene or a character introduction. This is when a character's inner monologue should be most present. In "The Solution, 9-11" is where it's most needed, as everything that happened was told to me but never shown. I was told what the imps were and their attack but I never experienced it. There's a slight improvement of this in "The Escort, 11-12", such as when you told us about Alex's linguistic teaching. That was the perfect time for that, but during the attack, when it should have been shown to us, it was instead told. "This happened, then this, and finally this." If you instead get us into Alex's head (what does he feel about what's going on? Does this give him conflict? Does it change his view of anything or anyone?), then you're already on your way toward showing.
