It really isn't a well kept secret that Catalina is dating Rhoda, is it? Of course, this begs the question of whether Elliot has actually met Rhoda or not. My answer is a defnitive maybe to be potentially clarified in future comics.
In any case, if anyone though they weren't going to see Ellen in a comic in this storyline, then they severely underestimated my view that Ellen totally had to have an on-panel reaction to Catalina kissing Elliot. I'm pretty sure I would be fined all of the dollars and thrown in jail if we didn't at least get a glimpse of this discussion.
