Infection and fall to the dark side
Ahsoka Tano: "All you told me of the Jedi were lies! Lies!" Anakin Skywalker: "No, Ahsoka! They were the truth!" Ahsoka Tano: "Says the man who told me the lies! And now I will kill you!" —Ahsoka Tano and Anakin Skywalker, after Ahsoka turns against Anakin.

Ahsoka was exploring the forest with her Master after the ship crash, when a small creature appeared and bit Ahsoka. Ahsoka fell unconscious for a few minutes before awaking. When she did her eyes had turned to black. Ahsoka then attacked Anakin and forced him into a bare area in the forest.
