The screen treatment in panel two was something I really thought hard about. On one hand, I wanted it to be recognizable that this was texting back and forth between George and Zoey... but in the ZR universe (and some other comics as well
) it's not Apple, but Banana that makes the de facto smartphones that people use. That made me want to change up the colors to yellows and browns-- 'cause you know, bananas. But I didn't for the first reason.
I realize that everyone reading this is several steps ahead of the characters in the strip and you have been well aware that George and Zoey are hiding the fact that they've been back together for some period of time... but there's things that we're leading up to that requires John and Lizzy to appear a little clueless right now.
It's on purpose.
