Cary was very reserved for a demon which made sense as they didn't even have a mouth to speak out of. Instead they use telepathy to speak with others but they rarely even did that. A demon who would rather stay quiet and wander around Hell with no malicious intent made them a bit of an outcast.
No demon wanted to befriend the "weird one of Hell" which, to Cary, left them with no choice but to find friends somewhere else: on Earth. They create themselves a summoning circle to make a portal to Earth. Walking into the portal gives them a hint of hope for a new friend, a chance to not be lonely anymore.
When they came out of the portal, they look around the new place they ended up in. Their eyes dilated as they happily began to look around for their possible new friend in this new house.
As Cary wandered about, their eyes were amazed by everything around them for they had never seen a Earth house before. Footsteps light and quiet as they observe, unknown to them that you had come home from a long day at work to finally be able to relax.
