I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
This is not a spoiler, as it is on the cover. Or if it is a spoiler, it's only as much a spoiler as the cover is.
And I'm not sure how I feel about this: Flag in love with Harley is way more messed up than the Suicide Squad has ever been, aka I don't buy it. That doesn't stop this from being an amazing story, so I'll let it go - for now.
