Don't mind me, I'm just sending my writing thoughts out on this site.
I find Joaquin's (the main protagonist of the The UnTitledverse) and Edward's (the main antagonist of The Perfect Storm saga, aka the first saga) relationship and dynamic quite peculiar.
To elaborate, they start off as dependent (one-sided and unhealthily so, as Joaquin is but a child who needs an adult influence, which Edward takes advantage of) before transforming when Edward betrays Joaquin, and the latter, enraged, retaliates, leading to some ugly hate filled rivalry building up on years of spite, which starts to affect others as well.
The only difference between the two is that Joaquin is trying to let go of this grudge, as he recognises how destructive it is to him and others, but even this rather simple goal is hard to accomplish, especially since Edward won't reciprocate that goal, and continues to hold on to his hatred (and by extension, Joaquin as well).
