Hannibal is anything but normal, he becomes incredibly anxious about public events, especially public speaking but once he's out in front and doing it it's almost like ghost is acting. Suddenly coming off as rather confident and knowing exactly what they're doing. This is something that he himself doesn't know how he's doing let alone that it's doing it.
Seemingly capable of acting charismatic and 'blending in' with those it needs to, it instead seemingly chooses not to despite how much easier it would be for ghost. This 'acting' however often makes him come off as more unnerving then when he's not doing it. As if it's not quite confident in it's act because it doesn't exactly understand how others function. He personally does not know what is considered 'normal' now and is almost too afraid to ask. He gets incredibly possessive of those who even share a small sliver of compatibility with itself, not that Hannibal's met many of these type of people.

Considering ghosts personality they don't really meet many people, but it does spend a lot of time over at his brothers house. The 'elder' Hannibal being known to just call him Jadis, seemingly by his surname, though that could potentially mean it's ghosts real name. Though it is also obvious that he does not correct people when they call the other Hannibal, so it doesn't really answer any questions when it comes to his 'true name'. However, through this constant visits to and time spent at his brother's house, he soon met Dr Whitlock and has become enthralled by the other man. It's clear to, apparently everyone but Dr Whitlock, that Hannibal is obessived with the man and possible also in love with him. Though doesn't seem to want to quite step over the boundries of stepping in on his elder brother's feet.

Despite his obessive behaviour and possesive nature towards Will when he spends time with him, this behaviour has caused Hannibal to be kept away from it, not that gho is very happy about this, though does also semi-understand where the elder Hannibal's thoughts on the matter. Hannibal also respects Will's opinions so doesn't want to make him uncomfortable, not that he's the best at picking these emotions up but ghosts very good at picking up others uncomfort.

Outside of spending time at his brother's, it spends a lot of time in it's own home. This is surprisingly small & quaint, in a small street filled with mostly older people whom he's become someone they often rely on to help them out when it comes to yard work. In return he's often fed by them and they also help out when he has issues that ghost needs sorting that gho can't do himself, such as contacting repair people. Even it doesn't quite know how he's ended up 'befriending' these people, especially as it spent a lot of time when it first moved in trying to get them to dislike him. What it does tend for greatly is it's garden, something that he prouds himself on, in both the front and the back, though it does get lazy with the weeding sometimes. Hannibal also likes to keep his garden rich and biodiverse for the wild life, not really mowing his lawn, as it's also not like it needs to use it often.
Outside of ghosts garden, it adores his book and film collection. Many of which Hannibal has actually been given as gifts from his neighbours after he refused money payments for helping them out, as he especially won't take this for helping out with their gardens. It's something that it does to relax afterall, so it doesn't see why it should take any praise or payment for any of it. When it feels irritated or like it's loosing control of itself, gho tends to send itself to a garden or the closest nature space to reclaim it's own headspace from whatever is overwhelming him.
