Before the fall and somewhat soon after, it was obvious he was a being that didn't think for himself. He was selfless to a fault, naive and didn't process certain emotions well (or at all). At first glance he's quiet and reserved, but if you're around him long enough he's proud, stubborn, and effortlessly caring to those he holds dear. He's learning to shake his people-pleasing tendencies and figure out what he wants for himself.

Isaac was once a proud, and dutiful angel, but after being cast from Heaven under the pretense of becoming a little 'too human' he became downtrodden and forced into adjusting to a lifestyle in hell. The fall was such a shock he blacked out the memory, and currently will become disorientated if such an event is mentioned.

After a couple days surviving through being attacked by half the Infernal encyclopedia, he was picked up by Death himself who tended to his wounds and offered a place to stay. He's been there ever since, and even though the reaper's intent is somewhat of a mystery Isaac has become absolutely charmed by him.
