Barely Glimpsed Siblings

A couple of characters from my old Misspent Youths comic book. If neither look familiar it’s probably because neither of them appeared in more than a half dozen panels in the five published issues. The young man with the shaved head is Treacher Murphy. The young lady is his sister Marta Honeydiver. They share the same mother but have different fathers. I don’t remember now (if I ever decided) which is the older of the two.
