@Strawberry-Otter Since Mani represents intellect and logic and there is another character mentioned by the name of Passion, is she a part of some ongoing story/storyline you have going on? What is it like? Also, since she's representing the kind of logical and intellectual side, how does she deal with her own emotions? Is she in touch with them or are they more like a bother to her she might not really know how to deal with?
He was under her dictatorship for roughly 40 years if not a bit longer! And it's a really long time for a human because we aren't made to be immortal or super long living, and he literally spent longer with her than he ever spent with his family. When he finally killed her there were people who asked about her and what happened to her, but Colin either said she passed away or left the place and left Colin behind to do as he pleased - he didn't really want to start getting into details, because killing her was a really big blow on his psyche even though he always wanted her dead. That being said, there were people who visited the hut and were really upset to realize Katherine was there no more because they were dependent on their medicine and services. Colin picked those up because he didn't know what else to do and he's a good boy deep down and doesn't like seeing people suffering.
It entirely depends on how he would become a human! Like if there is some sort of catch to it that is disadvantageous to him he probably wouldn't, but he does still wish to become a human! He has accepted the fact he most likely won't though and so isn't like actively looking for a solution anymore and just.. rolling with the punches. He has learned to be glad about things like being able to do soul related magic easier thanks to the state of his body and how his curse binds his soul already so he won't accidentally remove his own soul in the process.
He's aware he can be unsettling to some and come off as eerie & he knows he's a bit of a hermit and doesn't always know how to deal with others. He tries to be mindful of others and does put conscious effort into it but isn't always that good at it & with his body he tries to cover himself but especially at his hut he just doesn't bother doing that anymore
