"Yeah. And Mettaton, and Grune...lots of people. And I'm good at taking care of myself. And my friends." They smile at Sans-Serif gently. He really doesn't need to protect them. "Even though the castle's big, we can find our way around."

Huh. Even though they've called him a 'baby' before, they've never quite thought about how old he actually is. Someone who looks so much like Sans only being six years old is pretty weird to consider.
