Some stories, however things shake out in the product line, drop off from long planted seeds or even outright promises. I think about this sort of thing occasionally because I love "Abandoned and Forsaked" on the main CBR page, but really I was struck by cracking open Action #568 (been meaning to do that since Valentine's) and coming across the "Perry has Alzheimer's" thing I didn't remember.
...! Pretty fascinating how they capped off an issue with a line like that. This makes me also want to recall and explore that weird relationship with Lois from around the same time.
Between Crisis, Birthright, Flashpoint, Rebirth, and the general editorial scraps, which interesting plots abruptly disappeared before you got your fill of them?
