Death of Fleas
The Death of Fleas is the often-disregarded other lesser Death who survived Death's round-up at the end of Reaper Man. He was revealed to be, fittingly, a passenger on the skeleton of the Death of Rats. When Death of Rats is allowed to live on as a seperate Death, he opens a paw to reveal the Death of Fleas sheltering within. Whilst Death does indeed call back all the lesser Deaths with the exception of Rat, there is no definite objective proof that he recalled Fleas. given the historical association between Rats and Fleas and Death (rat-borne fleas are blamed for spreading the Black Death in a collaborative cross-species exercise that reduced the human population of Europe by a third) it would be nice to think Fleas is still out there doing the siphonapteran Duty.
