The military grade water vaporizer that the LOS uses. But that's a major plot device.
alternatively, His final test with the LOS and being under the influence of the blue flower and then being hit by the scarecrow's toxin later on and realizing the connection.
I think that ultimately the trilogy does a great job of introducing the LOS in begins and ending it with the LOS in Rises
