wellll...he's just a dietitian. boring stuff but it's interested him his entire life. he was a sick baby and toddler until doctors figured out he's Celiac and has a whey allergy. so his food has always been restricted. he moves in and out of the tricky waters of obsession with it. if he found out the world was ending, he'd eat bread and cheese all day until he exploded or however the world decides to end. oliver can be blunt and that can come off as rude or abrasive but he's mostly kind hearted. that's the plan for him anyway. that might change as i start playing him. he's a new character.
