"Obi-Wan believes...believed you were. Or are the Chosen One" Look, tenses when dealing with different points in the timeline are difficult. "He would not have lied to me, not even to comfort me as I died. You are the one destined to bring balance to the Force." The mention of being the last just confirms Maul's suspicions. "Is that not a form of balance itself? To destroy the Sith and Jedi both until only one remains to rebuild it all?" Yep, Maul was pretty convinced Obi-Wan had been right. This boy was the true Chosen One destiny had chosen.

Maul gestures for Luke to come with him back over to the door. "I think we both must look through the hole in the wall together. Only then will we be able to escape this room." Team-building exercise, yay!
