That's alright. The best theory I can come up with is that Seth was attempting to create a (or something akin to a) vessel of sin and Irina was made the demon while the cat was made the vessel (albeit a mobile vessel). Not a lot of evidence to support it though. Best explanation I can think of to explain why only those possessed (or used as the vessel of) a Demon of Sin can understand I.R. as the cat and how Abyss survived after her "body" was clearly destroyed. Maybe Irina couldn't be killed by just destroying her vessel and found a new vessel? If the demons were able to find vessels of their own, they have to have some degree of mobility, even if they are stuck in them (or refuse to leave) afterward.
