It's pokemon so I can't be like "omg this is a masterpiece of a character!" but Kieran hits home for me in a lot of ways, the meek loneliness and inadequacy turning into aggression. His obsession with becoming better. I think it's at least a very real portrayal of a teen wanting so badly to be seen. Or maybe I'm looking too deep into it lmaooo
Idk I personally would've done things differently in the second half of the Indigo Disk but overall I think nervous little guy turning into aggressive little guy in an effort to be seen as worth something is a fun trope and I hope Pokemon Masters gives us a little more closure than the end of Indigo Disk did. (cause I think he deserved better than "you're not the protagonist doesnt matter sorry")
