arthurs character traits/physical appearance defined in fanfics/fanart akin to jgls mannerisms : a self indulgent list :D
1. the entire fandom unanimously deciding on his ethnicity as jewish. and a proud one at that. I love how when he does the related rituals and celebrate the holidays, specially making eames fall in love with him even more. (yes I’m talking about that one fic where arthur marries eames in a coffee shop with witnesses and and whispering a prayer in respect to his religion)
2. the slick black hair falling to natural wavy luscious curls when freed from pomade jail, de-ageing him by about fifteen years. oh yes.
3. arthurs love for singing and dancing. both the fun kind and the professional kind. in line with being surprisingly bad/surprisingly good at karaoke. (someone is yet to make arthur take a guitar and serande eames with a ballad please do it thanks)
4. GLASSES. THAT ARTHUR USES CONTACTS AT WORK AND GLASSES WHEN AT HOME READING HIS RESEARCH. YOU ARE SO RIGHT!
5. arthur being a bit too long-winded and all adorably rambly when asked about something he really loves and cares about.
6. arthur randomly mentioning his love for batman comics or going to see batman movies (or someone finding long forgotten movie tickets to batman in his wallet) that’s the cutest thing I swear.
