I wasn't ready for either arc when I sat down to do a comic so I did a one off instead.
I don't know if I've done a strip where George and Lizzy were the only ones in it for the entire strip. I remember one where they were both putting on nigh mask cream
... but it had a cut away to John and Lyn. If there is one with the two of them by themselves I'd be surprised.
patrons at the $10+ tier already know that George and Lizzy have the same colored phone, so that was one detail I wanted to get right.
