after reading royce's bio, she'll probably be like "please don't come in here with the 'surprise me' mentality, because you will get water. surprise!" santana loves to get under people's skin to test how well they are under pressure, because she is a diamond - at least that's what she comes off as thinking of herself. hope royce has sly comebacks, because she's loaded with them. however, once you get past the tough exterior, she's know to lend a good ear, and is very straight forward when someone needs advice, no sugar coating. she doesn't take kindly to liars, so be very honest with her. otherwise, she can be the most petty acquaintance you ever did come across.
but as far as background - she moved back from california after being sent off by her father, after the discovery of the community of supernaturals came to light. basically, to prevent her from going down the same path of her mother, who was suddenly taken from her at six years old. santana is very conflicted with herself, as far as what path to choose - follow after her mother, or create her own. she started working at the bad apple two years ago after being a frequent patron, not only because she feels a part of a family she never quite had, but to investigate and find leads to what exactly happened to her mother. beforehand, she lived in los angeles with her uncle who was a cop, but also extremely talented in trades - which santana picked up and owned, like the boss bitch she is. lol, so she can fix a car, build an ikea bed, and even troubleshoot a computer that's having issues. can't guarantee it'll be a hundred percent right, but she'll attempt any challenge given to her, because frankly, she doesn't take losses very well.
all-in-all, she's back home to discover her roots and truths, and will interrogate anyone that she assumes knows anything about her family. it's the persistent side of her, and she should have been a private investigator, but she's a lot like betty from riverdale, and just gets into stuff she probably shouldn't... all for the sake of find her way.
i hope that kind of opens things up, still working things out with ~whimpers regarding her tenure at the bad apple, however she is bound to have some friendships or enemies at this point, lol.
