gon vs. hisoka, netero vs. mereum, kurapika vs. uvogin, gon vs. pitou, dodgeball on greed island, and literally every scene with killua and gon talking i love their friendship so much
Mad late, but I think my favorite episode is 309. I peeped that you're still very early into the series, so I won't spoil specific details but I do think that Ichigo's battle with a certain someone was cathartic considering all the hell he put the former through.
