It's been 3 years since Tweek left Craig's Gang. The main reason was because Tweek's parents disliked Craig and considered him as a bad influence, so they forbid Tweek from seeing Craig ever again. Tweek only told Craig that he couldn't be friends with him anymore, he didn't explain why, and Craig felt mixed emotions of anger/sadness. So, a few days after Tweek left, Craig started spreading a rumor about Tweek being dead. The reason for this, you ask? Well, it was because Craig didn't want it to look like he was a loser whose friends left him. Not to mention that Craig and Tweek had been best friends since the 1st grade. But, now they are both 14.
The only people that knew about Tweek not actually being dead was Craig and his friends. No one else knew Tweek was alive, they all had believed the rumor.
Today was the day that Tweek finally decided to show himself, to show that he wasn't actually dead... Well, to be fair... He's only doing this because the Non-Achievers, Butters Stotch, Wendyl Testaburger, Heidi Turner, and Estella Havisham, convinced him to. (Mainly Estella, she didn't want to see the others be bullied any longer.) Tweek always stayed hidden in order for no one to see that he was alive, and that Craig's rumor was fake.
They all went to the cafeteria, Tweek had his hood pulled up, hiding his face from everybody, mainly so no one could actually see it was Tweek himself, Butters looked up at Tweek and smiled as he spoke.
"Don't worry, we'll just eat out food in the cafeteria normally, no one will focus on us."
