oh, i like that idea! maybe she had a run in with whoever she inherited the office from while she was a peacekeeper a few years back and she recently ran into your girl and remembered her working with there too? they had a run in and started talking about the business and if you think it's possible, your girl could have mentioned either having a lot of cases on her plate or that she wasn't used to working solo and selina could offer to help out? and then they meet up at a later date to discuss details?
