Despite everybody claiming over and over, since several dozen comics ago, that Roomie has been trying to drag Lillian into bed, this is the very first time we actually see anything that might support such stance.
In other words, people have been trying to rush the inevitable... probably from the first time Lillian appeared on the comic ¬¬'
I wonder how long the comic will take before these two are a couple. In most comics I've read in the past, these two would just do the waltz around an eerily undefined relationship, feeling attracted yet never quite admitting it to themselves, as happened in so many comics before (online, on animation series, anywhere). In fact, their very goal, from the story-telling point of view, was to get the two main characters finally together.
Which is why I've always considered "Girly!" such a good comic. Rather than concluding the comic with a solidified relationship, the relationship was actually just the beginning of the journey. I wonder (and hope) that it will be a similar case. Yet, I have the feeling it may still take several more comics before these two are close enough to "tie the knot".
We'll just have to wait and see what Chloé has in store for us in the future
