AK vs. guy who refuses to call

[Warik]

Villain is 65 / 13 / 1.3

Should I have popped him again? With the exception of preflop, his play was consistent with AJ. Even if he had an ace with a weaker kicker I'd imagine he would have slowed down after my turn raise, but nope...

Was I too weak here or is a call down justified?
