Biography
Despite being a space station, the UNSC Hopeful was used by Jeromi on multiple occasions into battles, having no armament of its own, to save the lives of the critically wounded personnel aboard damaged warships. While he saved countless of lives, he faced a court-martial multiple times for his unorthodoxism. He gained and lost ranks during his career, having won a Colonial Cross twice. By 2525 he was a four-star admiral, and by 2552 he had become a three-star vice admiral.

He was a personal friend of Dr. Catherine Halsey, and helped her analyze hypothetical experiments on bonobos in 2525. He considered her his "star pupil", but he disowned her working for the Office of Naval Intelligence, which he considered as "selling her soul to the devil". Later, the same year, he sent her a transmission detailing his objection of the hypothetical augmentations and the dangers the augmentation process Halsey desired to a living organism. His experiments were later used in the SPARTAN-II candidates, although he was never made aware of it.

He was onboard the Hopeful in late 2552, when the Gamma Company SPARTAN-III candidates were sent to the station to commence Project CHYSANTHEMUM. There, he became heavily suspicious of Lieutenant Commander Kurt Ambrose.
