"my ... family's burden". Hmm.
Maybe you have me looking too hard at this, but I can see some subtle things that might support your theory.
In strip 1273, Julia looks worried and surprised when Roy says "you were there" when talking about his audition. A different look than if she just could not recall it. And in this strip when she says she is stuck "up here," that could be the cloudy demiplane Eugene is on right now, right?
I still don't think it is Eugene; otherwise, why would Roy talk about waiting for Julia to contact him in strip 1272? I thought they had some schedule set up.
