Miranda Lawson Headcannons
It's no secret that Miranda doesn't know how to be normal. She doesn't understand baking, how to give Oriana tips about boys, and, in the Shadowbroker DLC, we can assume she would suck so much on dating apps. (I know she was using it to get pregnant to try and prove she isn't infertile - but you get my point.) So here's my personal headcannons about Miranda trying to be "normal".
Her uniform has built in gloves so we never see her hands but I like to think she's shit at painting her nails. She can do it but it's messy and all over the place. She gets frustrated and doesn't like the feeling of waiting for nail polish to dry. She's learning so she can do this Oriana. Or just let Oriana do it for her. Oriana would definitely want acrylic long, sharp nails and confused the hell out of Miranda.
Miranda has a shit sense of style...she knows the basics: work uniform, armour, PJs, formal wear, and maybe casual clothes. But if you ask her to try to be stylish, she doesn't understand. She appreciates fashion, but doing it herself? She'll commit a fashion nightmare.
Miranda was genetically created for her looks. I like to think that makeup is actually not her thing. She knows the basics: foundation, mascara, and lipstick. Oriana would ask her about blush, contour, lip liner, concealer, eyeshadow, fake eyelashes, etc. Miranda would have no clue and just copy and paste the "How-To" beauty articles to Oriana.
Miranda would try her best to be a fun older sister but, at the end of the day, Oriana has to teach her to let loose. When they go shopping, Miranda would buy items that are more practical (like she's preparing for a mission) while Oriana buys items because she wants to waste credits.
Miranda would suck at all types of games - even if it's a first person shooter. "If this was real, he would be dead." "Why do I need to buy a DLC if I bought the game?" "What is so entertaining about slicing fruit as a ninja?" "Candy crush is stupid (she can't get past level 1)". She'll keep playing the games so she can be somewhat competent with Oriana.
Miranda doesn't know how to relax. She always feels like she needs to be working. Oriana has to take away her omni-tool and Miranda fidgets. Oriana lets her play with a needoh or fidget toy. Miranda, at first, is like, "What is this? I don't need it, Ori." But somehow she has a collection of them the next time they hang out.
Overtime, Miranda will learn how to be normal but there's always an element of awkwardness. She never truly perfects it.
