Yes! Walter! And good riddance to the other two. Actually, Wheatley found it all a bit troubling. See, Tyler was better than that, fawning on a human who did't really deserve it. Humans were good Test Subjects and good doctors, but to really care for one--

And Chelldon hardly counted. Chelldon was just a remarkably good Test Subject and therefore, Wheatley had to care for him and protect him as he was his source of 'Very Excellents' for the forseeable future! Never mind that they often, too often, embraced like Tyler was trying with the Chief.

Reckless!

Wheatley knew that Tyler was going to get thumped before he even heard the cry and disappeared out onto the catwalk with Chelldon.
