Jeeves

Jeeves was the butler of Pet, a 14 year old boy who ran for president of Canada. He later died in Chapter 15, let's get freaky, Jeeves, from a heart attack.

Little is known about Jeeves outside of his profession. His grave in chapter 21, Pet Sematary, that he likes painting, but "you wouldn't have known that from his poor character development"

There are 478 incarnations of Jeeves, the one we see in chapter 21 is the 456th incarnation. His reapperance in chapter 23, Coming out of the Clostest is the 458th, and it's revealed by Syo after the 3 year gap that the 478th version of him, as well as Pet, had died in an explosion. The other incarnations have died by "accidents" as Pet had stated, but no further information has been revealed thus far.
