they had issues about six years ago, when she was a padawan. her best friend was another jedi, and something happened that included getting her ass handed to her. the two left her for dead, so she's been pretty pissed this whole time, but slowly putting herself back together. but she took off from her parents at an early age to go do bad shit, so they could have run into each other any time. she could absolutely be after him, and remembers him from back in the day somehow. maybe wants to use him to get to ~beskar.
