I know, I know, I'm sorry. What I meant is... humans are advancing all the time, and by their own means, thanks to their brains learning new things every day.

[The door to his apartment gets open and Tank quickly comes out to receive his human and the one that sounds like him. Dave hurries to pick him up before he jumps on Hiccup, dropping a kiss on the dog's forehead.] Hello, beautiful. Miss me?
