While it’s true that Thing appears in this issue, he doesn’t meet Moon Knight and is completely inconsequential to the plot. Basically, he just admits to being a drug addict…
My guess is that the book, which was now a direct-market title, was suffering in the sales area and Editor in Chief Jim Shooter wanted to connect it to the broader Marvel Universe.
Marvel also ran an ad for the book that was kind of cute.
