"A diversion."

[The Only Real Estel]

I don't understand what the big deal is with this quote- it was merely clarification for anyone in the audiences who hadn't been fully tuned in for the previous three minutes or so. It kind of reminded me of how in Star Wars C3PO would always translate what R2D2 said into English in his reply, like:

Oh wow! Do you mean if I pay really close attention I can understand what R2D2 is saying? That way I can laugh at C3P0 for repeating something I already understood? Or will I still have to really on C3P0 to translate, since R2D2 doesn't speak a language I can understand (unlike Gimli, Gandalf, & Aragorn)?
