dianna was born as the second child to morgan and victor delmino. her older brother, harrison, was barely two years older than her, which meant that the two of them grew up being quite close. the fact that he was her older brother never escaped her, and it was often with frustrated sighs and tantrums that dianna would watch as her brother got to do and learn stuff before she could.

growing up in the delmino household, dianna and her brother had it pretty good. their parents worked hard to provide for them as well as give them an enjoyable childhood. to most, it would have seemed like they were the happiest family ever, and even dianna thought so for years. but as dianna got older, she started to notice the constant bickering, which only seemed to escalate over time quickly became too much for the parents as well as the kids. dianna was just shy of 9 years old when her parents filed for divorce. victor, her father, moved from their home in tarrytown to Dobbs Ferry in order to stay close to his kids and to make the shared custody easier of them with school and everything. The last thing they wanted to do was make the kids choose, so they figured it out that until the kids were 18 they would live officially with Morgan and could spent 2 to 3 nights at Victor's house of their choosing a week. It worked out for a while, they mostly did weekends at dads house and sometimes would do a weeknight if Victor had the ability to get them to school the next morning.

in the younger classes, dianna was quite the avid pupil. she loved learning new things and loved getting gold stars whenever she achieved something. her love for learning never went away, though over time it lessened as her focus shifted to the extracurricular activities the school had to offer instead. joining the photography club and the dance team quickly became her top priorities, much to her parents dismay who both wanted her to excel academically. she tried to get a yoga club started, but couldn’t find enough pupils who wanted to join so the club never happened.

her dad remarried when dianna was still in high school, and though beth, his new wife, was actually pretty decent, dianna couldn't quite cope with it at first. she had always deep down hoped that her parents would get back together. over time, she came to accept that things were as they were and that there was nothing she could do to change it. and with time, she could also see that the divorce had probably been the best for everyone involved.

upon graduating from sleepy hollow high school, dianna was left with the choice of going with a community college or an out of state college. in the end, she decided to follow in her brother's footstep and went to pace university where she wanted to major in sociology/anthropology with a minor in photography. next to her studies she got a part-time job at a the library in tarrytown. she had always loved books and reading, so when the opportunity came, she jumped at the chance. she graduated from uni in 2015 and kept the job at the library while trying to pursue a career as a photographer on the side.
