There almost seem to be two sides to Roz based solely on if she's on or off the clock; obviously when she's working she can't parade around looking like she just got done trawling through back alley biker bars which is why she comes off as fairly clean cut despite her off-the-clock hobbies and lifestyle. Working Roz often sports a blazer and a skirt - or sometimes pants - and a smile that blends the line between genuine and manufactured to come off as 'safe'. Her eyes, a muddy brown, seem to brighten and come alive when she's giving tours or, really, whenever she talks about something that really takes her interest. Roz has been told she's tall for a woman, standing at just shy of a flat six foot, but hearing that just makes her shrug and wish she could've cracked that six foot ceiling. She doesn't have any tattoos to speak of but there is a horizontal scar on the top of her right arm that probably needed stitches as it never quite healed fully and there's a slight pinkish discoloration forever on her; fortunately it doesn't hurt both in the physical sense and in selling the whole 'cool girl' vibe that she has off the clock.

When she's away from the job, Roz tends to dress a bit like a cliche but it works for her. Leather jacket, denim jeans that may or may not be snugly fitting, hands in pockets, black hair more windswept and uncaring rather than immaculately maintained, and really putting in work to look like someone that walked out of an indie album cover. It's difficult to say which is the real Roz as she feels comfortable in either attire, and perhaps that's the most important part.

Rosalyn Ballard was fortunate enough to find her first love at a very young age and that, like anyone, was Henry Walton Jones Jr. otherwise known as Indiana Jones. Her father took her to see a screening of Raiders of the Lost Ark when she was ten and that was when she said she wanted to be an archeologist which lasted up until she was told that real archeology didn't typically involve punching Nazis and faces melting. It was disappointing, to be sure, and for a time she thought about getting into acting, but after getting cast in a junior high production of Treasure Island as Billy Bones of all characters and realizing she died ten minutes in, her acting dreams died there. Still, her fascination with Indiana Jones is what led her to anthropology and rather than become a teacher, she opted the tour guide route which is sort of like a teacher except she doesn't have to deal with kids for eight hours a day.

Roz has been a midwest kind of girl her entire life, growing up in a boring suburb until the great divorce of her parents when she was thirteen. She went with her dad which involved moving in with her grandmother until her dad got back on his feet. Unfortunately he never did, thanks to being the victim of a DUI accident. What was supposed to be a temporary situation with her grandmother turned into Roz living with her mother in downtown Chicago. Her mother, a banker, tried to be Roz's friend first and foremost and Roz really just thought that was kind of lame; Roz didn't need a friend for a legal guardian. They got along well enough but it was clear that Roz was a bit of a daddy's girl and considering that they bonded over Indiana Jones and Dead Milkmen records, it was hard to blame her.

Not a standout student in high school with no real extracurriculars to speak of, she still got into UIC and got her degree in anthropology. She had planned on going on a backpacking trip to celebrate but it wasn't meant to be. The money she had saved up for it since working part time in high school through to college (all from the same place, a local chicken shack that also came with the benefit of her working numerous Tastes of Chicago in her time) was used instead to help support her mother's legal fees after she did a hit and run. Fortunately for Roz, she had enough to put a down payment on an apartment and within the next two weeks not only had she moved out and left her mother to fend for herself, she had found employment at the Field Museum - where she continues to the day.

While Roz certainly enjoys her life, the fact that so many of her dreams have been compromised or cancelled is an unfortunate reality and has colored her outlook even if she'll never admit it. Roz doesn't feel the need to aim any higher in terms of career or stability because she believes that if she does that it'll amount to nothing. Sure, she would've liked to be an archeologist but it wasn't like the movies. Sure, maybe she would've liked to be in the movies but if she couldn't land the lead role then what was the point. Yeah, she would've liked to do an anthropology backpack trip but why should she get to get what she wants when her mother needed her help for a little bit. Why bother having long relationships when her first serious girlfriend cheated on her. It's not cynicism, it's bitter realism that nothing she wants really works out so she takes the pleasures in other ways, such as her work and going to punk shows in crappy bars on the weekend. It's not the life she envisioned, but maybe one day she'll treat herself to a vacation.

Roz was a smoker in her college days because she thought it was 'cool' and she has since quit.

She thinks people are too harsh on Kingdom of the Crystal Skull.
