Would your character possibly have visited the Jedi Healing-focused academy on H'Ratth anytime between 4 and 8-10 years ago?
If so, then he might've encountered Lea. Before going to Alassa Major with her master 4 years ago to study and practice finer arts of diplomacy/politics and social interaction among the Republic's elite, Lea spent pretty much her entire life in that academy.

Any other characters can also answer that if they think theirs may have visited there too.
