Now methinks King khandu has been cloned. The reason for his long absence has been made clear. The old King khandu would have said:

Constipated? Me, constipated? You're the one that's full of shit! And if I need a Royal Enema Deliverer it would be you, jerkoff!

And, while it's certainly nice not to be abused and belittled, I am a little concerned about this kinder, gentler khandu. Gotta be a clone.
