Today's strip actually lets us know a lot about Elliott. We see that he plays the ukulele (one is leaning against his couch). He has a cabinet full of fairly thick-looking books and he has a record player on top, suggesting that he's into classical (60s to 80s) pop or rock.
What is very interesting is that he lives in the same apartment block as Melon and Roko. I wonder if he knows the lonely Officer Basilisk? More importantly, I wonder if he knows about her need for bread? Whilst Melon doesn't strike me as someone who will share around others' private business, if she and Elliott get talking, it make come out in some context!
Meanwhile, Melon strikes me as more and more like early Hannelore with less OCD and some more exotic issues with reality and social boundaries. That said, I'm wondering if Hannelore is a big of a guide to what is actually happening here: She ultimately imposed herself on Marten and Faye because she was desperately lonely. Given that Melon told Roko that she and Arthur apparently don't have much (if any) furniture in her apartment, maybe Melon's real motive is to have someone to interact with rather than just sit in an empty room and be random with her friend?
