"Once again, the Jedi Council proves they can’t learn from their past mistakes and start blaming the Exile for everything. What happened to the Master Zez we talked to on Nar Shaddaa, who regretted sending the Exile away? And the amiable Kavar on Onderon, who was starting to admit they f***ed up? They did a complete 180 here."
