But didn't
T3-M4 find the Exile? According to the TOR canon, T3 couldn't find Bastila, so he found the next best thing: the Exile who had a history with Revan.
Even so, IMO this was a flaw in TSL - nothing was built on either concept
(1. Atris orchestrated the Exile's return... How exactly?)
(2. T3 found the Exile... Where exactly? How exactly?)
