No, Cartman tells Stan but Stan never feels compelled to believe it. Even throughout raising Seth as a baby Stan thinks she might just have postpartum depression. Despite her distance from Seth she still teaches him somewhat. Sharon and Stan do most of the upbringing though.

He’s just fucking around figuring his life out and experiencing the world in his own Kenny way.

He’s a sweet little bundle of joy~

Nope. Wendy and Craig were a good couple but Tweek and Craig had been experimenting for a while. At first Craig experimented with Kenny since they had such similar faces, but it wasn’t Tweek so that wouldn’t do. Seeing Tweek interact with Cartman made him progressively more jealous so he started going for him. Wendy eventually found out and dumped Craig.

Tweek ends up with Craig. Clyde has a hard time finding a guy in such a small town. He tries Butters for a bit but they don’t work out. He’ll probably just live his life and go on Grindr sometimes until he finds a good man.

Because Butters was clingy and unstable when they were together and he didn’t want Butters to do something irreversible if he saw Kenny die.
