Who exactly is this Sai person? I'm only on episode 126, so if that makes it a spoiler, don't tell me.

Sai is Sasuke's replacement. He took Sasuke's place in the squad.

ya he is sasuke replacment and since your only on 126 of Naruto then ya you don't want to know anything else until like oh maybe 30 episodes into shippuuden maybe could be more could be less i don't really know

he’s a Anbu that shows no emotion and attacks with pictures
many belive him to be gay
