EDIT: I somehow misread the last panel of my own comic, and the commentary reflects that. For some reason, I read it as Grace not recognizing that it was Tedd, but she totally did. There's another reason I can think of for why I misread it which I will elaborate on when the time is right, but for now, enjoy a commentary based on me having misread my own work. HOORAY!
Panel three of this comic feels both out of character and in character for Grace these days. It's out of character for her to put things that way, but she does get strangely serious at times while playing video games.
Something that does annoy me about this comic is that Grace totally should have recognized Tedd as the woman dancing. Tedd's face basically doesn't change when he's female, and that's not even a retcon given that Elliot couldn't tell the difference earlier, either.
Of course, the obvious explanation is that Grace was so focused on her game that she barely got a good look at the video. Yeah, that's the ticket...
