marcelina's accent is a confusing mix of southern drawl, twangs of korean, and the more solid-flowing californian. when she's under the weather, drunk or upset, she sounds certifiably texan.
marcelina's first language was not english, but korean. her mother tried to teach english to her at about four years old, but was never entirely fluent herself. the bits and pieces her mother couldn't grasp to teach her were learned from late night sitcoms and the help of a very patient kindergarten teacher.
despite being fluent in english for decades now, marcelina occasionally gets tripped up with syntax and grammar. she'll never admit this, because she rarely admits a weakness, especially when it comes to her intelligence. nonetheless, it can occasionally be obvious if she's not paying close attention.
marcelina has a long surgical scar down the front of her stomach. she is extremely self-conscious about it, and will usually go out of her way to keep it hidden. if she really wants to wear clothing showing her stomach, she hides it with makeup.
erratically fearful she will be abducted in the middle of the night, marcelina has to check the doors and windows twice to make sure they are locked before she can sleep. this made childhood sleepovers very awkward, and adult sleepovers even moreso.
marcelina's only "real" job before her doctorate degree was a four year stint at sephora. thanks to that time, she is surprisingly skilled at makeup and will often do work for her friends if they have a big event to get ready for.
marcelina is nearsighted. she never wears her glasses because she thinks they make her look funny. because of this, she keeps them in her car solely for when she's driving.
