He wouldn't want us to cry. He'd want us to be strong. Learn to make onward with only his memory. His video title was very casual about it, and I think that's how he wants us to feel. (Think "Technoblade has left the game.")
This is a theory ofc but how can a man downplay his death with his last words to us being "so long nerds" for any other reason? We'll all miss his shenanigans, but we'll stay strong for him.
