[Action]
[Is it? Sasuke doesn't like letting other people get in the last word, but this conversation needs to end. And Itachi is giving him a way out - thank you Itachi - and at this point, that is just what he needs. A way to pretend this conversation never occurred, and to go back to the degree of normalcy that existed before.
With just a hint of relief, and a bit of exhaustion (seriously, talking to all these people is just - no, way too much):]
I don't intend to pursue it further.
[Continue if you like, Itachi, but Sasuke is tired of dealing with people other than you.]
