Back to Deidara,one thing I got to remember is that she's from the Akatsuki.. A group of S Class ninjas.. I don't think she will go down without putting a fight,at least in my opinion 2 chapters long.. Especially Kakashi's misfire when he was aiming for her head,ended up hitting the other arm.. On the other hand,it's only 2 years that Naruto looks older but as we all know our dear Naruto tends to concentrate too much on Kage no Bushin & Rasengan.. I feel that he'll grow up eventually,just raging hormones.. hur hur hur..

Kakashi may have attained the Sharingan from Obito but doesn't have the Uchiha bloodline to fully control the Sharingan,thus he tend to use up a lot of Chakra in order function it fully .. Anyways it's not surprising that Kakashi can attain MS..

Kudos..
