Chapter 4
The characterization in this chapter was great, we get some backstory on Sam and learn that he's managed to become quite the battler and he's caught many new Pokemon. Vlam's evolution was because of his victory prize Fire Stone gift to Tommy. Indeed, the death of their father has taken a toll on not just Sam, but Tommy as well basically a lack of attendance at school has caused him to sadly fail. He gave up his future for his brother's sake, that shows the bond and emotion between the two and it shows he really does care a lot for his bro. For a second, I thought you were referring to Sam's Tangrowth rather then it being Miah. Sam has a tourney coming up, that's something to look forward to. But, overall a nice chapter for some character interactions and such. Barnabus is a unique name.
Chapter 5
Nice in-depth description at the beginning of the chapter. I like how he's a tad sensitive about Vlam and Bree being Poke Ball'd and how the Lake Trio being caught is such a sensitive matter. My previous speculation regarding Tommy being dead turned up true, interesting to say the least. Well, not so dead more so, immobile I guess. Interesting, so these are Sam's goal, finding the Lake Trio to help heal his paralyzed brother. It's a shame he forgot his Pokemon and everything ever since the stroke, what an awful thing to happen. I wonder how Sam is going to even attempt to catch legendary Pokemon, they're elusive and extremely powerful. He'd have to put up a hell of a fight to even weaken one, so I'm looking forward to the next chapter for sure.
