Makayla was originally introduced in Season 8 of Chicago P.D. Unfortunately, her introduction was marked by tragedy. Her biological father is currently serving a life sentence after killing Makayla's entire family. Having witnessed the murders herself, Makayla is often suffers from night terrors. Throughout the course of the show, she's adopted by Burgess and Officer Adam Ruzek (Patrick John Flueger).
Season 9 sees Burgess trying her hardest to provide for Makayla — and that may or may not include drawing lines with her on-again/off-again relationship with Ruzek. In Season 9, Episode 10, Burgess expresses a desire to have "more boundaries with Makayla."
Of course, this puts Ruzek at odds with Burgess yet again. As Ruzek wants to provide for his adoptive family, he still has some issues to work out with Burgess.
Right now, "Burzek" isn't a thing, and that rift between the officers could certainly impact Makayla. At this point, Burgess is willing to do anything to ensure Makayla's well-being, especially as she still recovers from her attack in more ways than one.
Chicago P.D. airs on Wednesdays at 10 p.m. EST on NBC.
