In the finale of Star Wars Rebels season 2, Ahsoka confronted Darth Vader and part of the conversation went as follows:
Darth Vader: Anakin Skywalker was weak. I destroyed him.
Ahsoka: ...Then I will avenge his death.
Darth Vader: Revenge is not the Jedi way.
Ahsoka: I'm no Jedi.
Darth Vader's response to Ahsoka's desire for revenge feels somewhat odd to me. Why would he care to remind Ahsoka of that point? I guess it may not exactly be out of place for Darth Vader to say that, though I cannot exactly fathom why he would. Or is there a remote chance that, already at that point, the Anakin within him has already surfaced, trying to dissuade Ahsoka from this path?
Who is the one speaking that line: Anakin Skywalker or Darth Vader? And why?
