Not to himself, but to other people. Specifically Jasmine.Before she joined the manor as a maid Tyson’s father (the late Professor John Delaney) had him studying mathematics all day every day. Once she came to the manor she took on the role of a surrogate mother for Tyson, as Tyson became a surrogate son for her, and decided that he needed time to be a normal boy rather than just studying mathematics. His father reluctantly agreed so Tyson got Saturday and Sunday to do whatever he wanted to do.Tyson didn’t have any real friends so spent most of his free time with Jasmine: helping her clean, going shopping with her, et cetera.On Sunday mornings, when Jasmine went to the market for fresh fruit and vegetables. Tyson always went with her so it became a habit that he would help her get ready in the morning by doing her make-up.He also knows how to do foundation, eye-liner, and everything else, but he was always best at applying the nail polish.
From Jasmine’s side of things, it left her hands free to write up the shopping list for the week and gave her an excuse to see how shaky Tyson’s hands were, and how anxious he was that day.
Tyson knows how to do make-up, because he used to help Jasmine put hers on in the morning.He finds it therapeutic to apply make up to another person; not that he ever puts make up on himself for any other reasons than disguises on missions and/or to cover up wounds, usually from those missions but sometimes from clumsiness.Tyson isn’t, and has never been, a morning person. He doesn’t like having to think until he has caffeine in his system, applying make up isn’t something that requires too much concentration. Some parts do, but Tyson always leaves thought parts until last when he’s a little more awake.He likes to feel helpful and applying makeup for another person makes him feel useful.
