Lemme get this straight. You're saying Slughorn retired because
Voldemort killed Lily? Minor continuity error here. Snape had been
teaching for 'fourteen years' as of September Harry's fifth year. Ergo,
he was on staff for two months before Lily died. Ergo, Slughorn retired
two to four months before Lily died. Ergo, there was no connection
between the two events. You might want to fix that.

Whatever Happened to the Slug Club? (Author Response)
Thanks for reviewing. That's a very precise interpretation. Two months is enough leeway in the approximation of 14 years that they could be connected. Anyway, the spirit of the story is that Slughorn's judgement about a student had been so wrong - and he certainly knew Voldemort was a rotten egg before Lily died.
