As of now, September 20th 2009, Naruto Shippuuden current episode is 126.Episode 124 will air on September 24th.
Tobi and Deidara appear at the end of 122 and the fight is from 123 to 124, where Deidara dies..
It depends who you are talking about, Sasori (the puppet guy) dies in episode 28. While Deidara (the dude with mouths on his hands) dies in episode 124 in a blaze of glory.
he dies somewhere between shippuden episode 124 and 126.
Episode no. 124....!!!!
in shippuden(second anime series) deidara fights sasuke, and in order to kill him(which he still didnt succeed at), deidara uses his strongest technique, C0, which causes him to blow himself up. this happens in Naruto: Shippuden episode 124, and in Manga chapter 362.
deidara appers in the naruto shippuden episode#2 for the first time so he appers the most in the gaara rescu arc,in the other episodes he appers just as a hologram on akatsuki meetings,then he appers in person with Tobi in shippuden episode 99 and 112,then comes his fight with sasuke so episode 122,123 of shippuden,his last appearenc is in episode 124 where he dies.....he comes back to life along with itachi,sasori,kakuzu and pein but only in the manga in the fourth shinobi world war arc so soon there is going to be more action for him,better read the manga because everything happends in it faster.
There aren't any episodes with them together like talking, but there is one with Itachi, Kisame, and Sasori trying to talk Deidara into joining the akatsuki in Shippuden episode 124. And there is a few episodes in the beginning of Shippuden where they fight different people indirectly.
the first time naruto and sasuke fight is in the third episode of season 5, ep. 107 The Battle Begins: Naruto vs. Sasuke.Then again from the end of season 5, ep. 128 A Cry on Deaf Ears through the beginning of season 6, ep. 134 The End of Tears. the following meeting between sasuke and naruto occurs at the end of season 2 of shippuden, ep. 51 Reunion, and a fight between the two ensues in ep. 52&53 The Power of the Uchiha and Title of season 2. in america, shippuden is in it's 10th season, so far naruto and sasuke have yet to cross paths again since the last time in season 2.hope that helps :)
In episode 123-124
