Jonesy

Jonesy is the supposed name of a calico cat aboard the. It was probably a pet of someone onboard the Autumn and was onboard during the Battle of Reach and when the Autumn reached Installation 04.

However, Jonesy's owner had lost her by then, although he put notices on the Bulletin Board to alert other personnel to the lost cat. Jonesy is assumed to have died either during the Battle of Installation 04, during the Covenant boarding, when the Autumn crashed, the Flood Invasion, or when John-117 and Cortana initiated the catastrophic destabilization of The Pillar of Autumn`s engines that destroyed Installation 04. But in Halo 3, there are posters for a cat by the name of Jonesy, which may be a hint that she is still alive. However, for a cat to have survived that long is extremely unlikely. There is also an apparent silhouette of a cat in the bottom right hand side of the poster, although it could be a black cat.

Trivia

 * As almost all calico cats are female, it is assumed that Jonesy is a female cat.
 * On the level Crow's Nest in Halo 3, there is a pile of garbage located near the toilets in the level. One of the pieces of rubbish is a note which is half covered up, but reads "Still missing my cat Jonesy". This is most likely an Easter Egg.
 * Jonesy's owner may be Pete Stacker.
 * A similar poster can half be seen in the trash on the the left side of Foundry facing the fans. You can see a picture of a cat and the word "missing" and "onesy".
 * The poster can be seen on several other boards throughout the level Pillar of Autumn.
 * Jonesy is an obvious reference to Lt. Ripley's cat, Mr. Jones, on the commercial towing ship, the Nostromo, from the movie franchise Alien. Bungie has been theorized to have borrowed many aspects from Alien and its sequels as a basis for the Halo series.
