Tedd had to go. His home planet needed him. That, or he's just off panel, and saved a little production time by not drawing the guy without any lines this page.
I do not know why I like Sarah's phrasing in the last panel of this comic, but I do. Some corner of my brain said "yes. Yes."
I had no idea where exactly the dialogue on this page was going before I wrote it. All I knew was that I wanted to establish that Ashley and Elliot had plans to just hang out at Elliot's house and watch movies. The rest wrote itself after I wondered whether it was awkward and/or rude to talk about this in front of Sarah.
