Need your help please?!

Delilah Jaywurth is gonna be a character in my JanNo novel but I know literally nothing else about her.

Could you help me out with an age range she would be and her relationship to the MC pretty please?  It only needs to be "early 20's and she's the MC's accomplice" or "late 70's and she's the MC's mentor" or something like that pretty please?

Thank you!
