I'm sure there's a thread somewhere about this, but really, who has time to search through thirty pages of threads to find one relating to this topic?
Josephine says her husband Ike, or Isaac Anwhistle, was eaten by the leeches. But in TSS, Lemony says that Isaac Anwhistle, who everyone called Ike, threw the sugar bowl out the window of V.F.D headquarters.
So why did Josephine think he was dead? Is he dead? Am I missing something?
TSS does not name the person who threw the sugar bowl out the window. LS lists three volunteers, one of which is Ike.
"And none of the Baudelaires would ever meet some of the organization's most beloved volunteers, including the mechanical instructor C.M. Kornbluth, and Dr. Isaac Anwhistle, whom everyone called Ike, and the brave volunteer who tossed the sugar bowl out the kitchen window ..."
Although that still leaves the mystery as to how Ike would still be alive. Perhaps it was a gaffe on DH's part, or perhaps Ike was the "survivor" that Quigley spoke of after all.
It's not a plot hole, it just means that at some point Ike Anwhistle was at the V.F.D. headquarters. It doesn't mean he was there right before it was destroyed - but even then, Ike's death was probably only a few months earlier, maybe even a few weeks. In a better world it's entirely plausible that the Baudelaires could have met him at the headquarters.
