He made a goodbye video saying that he was going to be doing other projects. I guess it's nice that he still shows up on GT live but he's not the host of all the theory channels anymore so it's kind of like the end of an era. I do like all the new hosts though :)
I'll have to check that out. the end of an era! *rips hair out* WHYYYY lol hopefully by miracle he makes a video titled "hello" instead to follow up the goodbye video haha
