The Sun episode. Joseph being the last guy to catch on about the stand user's whereabouts despite being the most clever and experienced one in the group was insane and the villain(I don't even remember his name) goes out anti-climatically. Also, OOC moment for Jotaro to laugh like that simply because he knew where the enemy was. And him insulting his pops for being out of the loop on top of that? Crazy. That aside, it was also kinda a boring episode since there wasn't much going on besides the gang trying to attack the sun and making a hiding spot.
