It was a request for slash and/or gen with canon het, she wrote the canon het. Like the shipping is not the problem here, it's the gleeful murder of the favorite character, and it's weird that coal always talks about it like it's the shipping. if she'd written it as hateslash and still gleefully run the guy over, requester would probably still have been (rightfully) upset.)

(Which I guess is another reason to point out that elaborate DNW lists don't fix things like this - she would almost certainly have respected a no het DNW. And still gleefully run him over.)
