Jonas

 (died August 17, 2277) is a resident of Vault 101. He is the son of Anne Palmer and the grandson of Lucy "Old Lady" Palmer. Jonas is a friend of James, the father of the Lone Wanderer.

In the 2260's, Jonas is an engineer working on the Reactor Level.

In April 2268, Jonas finds a BB Gun in a storeroom on the Reactor Level.

On July 13, 2268, Jonas greets the Lone Wanderer in the generator room on the Reactor Level.

In the late 2260's, James is appointed Jonas as an assistant by the Overseer in an attempt aimed at curbing the excesses of the vault physician by having the assistant act as a voice of reason. Jonas and James forge a friendship very quickly. Together as partners they work at examining and treating patients, and conducting routine experiments testing the health of the Vault. For an unknown length of time, James deliberately keeps his assistant in the dark on covert experiments aimed at reviving Project Purity. Eventually, Jonas grows suspicious of the physician's activities. Sometime, in mid-2274, for the first time in their relationship, Jonas aids James with experiments related to Project Purity. James hopes that Jonas understands the situation he finds himself in by helping the physician; however, James feels, regardless if Jonas understands or not, that the point of no return has been reached and that Jonas is with the physician to the end.

When James escaped from Vault 101, Jonas was murdered by Officer Mack on suspicion for aiding him in the escape. A tape can be looted from Jonas's body, containing a message pertaining to James' escape. The player can also collect his glasses and a Vault Lab Uniform if they are willing to strip these from his body.
