While studying for my chemistry exams I came to the realisation that Jolyne is a hydrocarbon. Where, Jolyne’s basic form is An alkyne. Alkynes basically have the suffix ‘yne’ just like Jolyne. Eg: ethyne, 1-propyne. Hence, Jolyne is an alkyne. Also, during the end of Stone ocean, she is known as Irene which implies that she has now desaturated to an ‘alkene’. Alkenes have the suffix ‘ene’ just like Irene. Eg: Ethene, Propene. There are many proofs that this is true. During the fight with Rikiel, she sets herself on fire which is a property of hydrocarbons. They are combustible and are used as fuels. Also, Anasui once said she smelled nice, just like an aromatic hydrocarbon. She got caught masturbating, she couldn’t do it without lubrication. Guess what? Wax, petroleum-jelly are hydrocarbons which are used as lubricants. During the ‘Made in heaven’ fight, everyone is shown dissolving and decomposing in water except Jolyne (Her limbs and glasses were broken, but she was never shown decomposing). This was because hydrocarbons being non-polar do not dissolve in water. Jolyne could also uses her string in different ways to her advantage, just like isomerism in hydrocarbons. Hence, Jolyne is a hydrocarbon.
