Desmond's Links
He is always happy to talk with Nathan, because it makes him happy. However, he is deeply concerned for his health and safety, but he doesn't have the guts to confront Nathan's mother about his concerns.
Seeing as Nathan never really had a proper father or stable mother to take care of him, Desmond realises that he should help Nathan as much as he can, so he can live his best life.
He learned most things about his late father from Desmond, as well as a few life lessons... Maybe.
He has always felt uneasy towards Forias. He is always concerned about her, but he is too afraid to make conversation with her.
She doesn't hate him, but she doesn't like him either.
Desmond used to have a slight crush on Florence back in the day, but knew that Florence never felt the same way, so he remained silent about it.
After Florence's death, he had always felt horrible thinking about it. Part of him thought it was his fault, and even talking about the death makes him grow upset.
The best of buddies.
Desmond didn't find Samson to be a good person at first, but once he had to constantly check up on him, he had realised that Samson has a hidden kindness inside his asshole exterior.
Doesn't like being checked up on, but Desmond is the one who keeps him alive.
