How 'bout for Trickster, A10, A13, B7, and B10?
Thank you for the questions! Always love to do stuff with Julian c:
A4 - Fears/phobias
As stated in Julian's bio, they're extremely afraid of aliens! It's mostly because of their exposure to the internet as a young kid, and the result of seeing some unsavory things that scared them to death. Along with this - they're also afraid of being stuck! If it's a smaller area (like, getting your head stuck in the stairway rails, or getting your fingers stuck in one of those tables with the holes in them.) Julian's afraid of accidentally getting stuck and having to cut off their limb, though it's a bit of an unrealistic assumption.
A13 - How they behave when angry
Julian get's pretty loud when they're angry. They can't bottle up their emotions, their reaction would be way worse if they did. Julian's pretty confrontational, and will get in arguments with people.
B1 - What relaxes them
They like learning new things! Reading about the smallest or dumbest fact can help them calm down.
Also ice cream. Mint chocolate ice cream..
B7 - Habits
Julian likes to click their tongue and make other mouth-related noises, they like to make little tunes with this. They also tend to keep themselves locked up while doing experiments or similar, and continuously forgets to take care of themselves.
