You could branch out further. If you tell her your the dark lord, you get dark side points. If you don't tell her, you get no alignment change. You could also have her find out through a high ranking 'friend' in the sith because if you are light sided, idt you would tell her your an ex sith Lord. Just some food for thought
It is never actually elaborated on how Jolee knew he was revan or even how he knew who revan and malak are (considering he was in exile on kashyyk well before the mandolorian wars). I always assumed that he may have met or spied on revan and malak when they were looking for the star maps the first time and somehow saw revan with his mask off. Seems like the best answer for how he knew the galaxies recent history so well. Meeting him may also explain why he willingly followed revan and tried to help him as he may have seems something that convinced him in his first meeting
