So in season 3 we have 3 episodes that actually take place during the same time.

During episode 7, 8, and 9 all of these episodes take place during the same night, the night of the meteor shower.

Each follows one of the four main children’s story lines.

7 follows Cartman while his mom is at the meteor shower party featured in episode 8 he is baby sat by Shelly

8 follows Stan saving his parents and everyone’s parents from being killed because they are mistaken for suicidal. At the end of this we see Kyle with his Jewbilee outfit and he wants to tell Stan about his night.

9 we get Kyles perspective and we get to find out what happens during Jewbilee. Kenny comes too but don’t wanna spoil anything
