seeming as the next chapter is called "Breakdown..."!!
i went to dictionary dot com to see what meanings it came up with and they are quite interesting...and to do with the next chapter in ways!

1a. The act or process of failing to function or continue.
1b. The condition resulting from this: a breakdown in communication.
2. Electricity. The abrupt failure of an insulator or insulating medium to restrict the flow of current.
3. A typically sudden collapse in physical or mental health.
4. An analysis, an outline, or a summary consisting of itemized data or essentials.
5. Disintegration or decomposition into parts or elements.
6. A noisy, energetic American country dance.

1a. can be related to sasuke or naruto...naruto getting impaled sasuke thinking he is dead runs off...or sasuke goes for another chidori and he cant do another and he gets stuffed up...or naruto cant move and is sinking to the bottom of the lake.
1b. breakdown in communication...ahhhh not much needed to say here..
2. or kyubis chakra stops the flow of electricity from the chidori and hasnt impaled naruto but just taken a nip outta naruto and narutos grabbed sasukes arm or of the sought...
3. sasuke collapses dues to the CS1 OR 2, or the chidori, or is having mental breakdown...naruto goes full mental kyubi taking control kinda thing and/or impaled by sasukes chidori sends him in the water then has a kyubi outburst...

but i think 6 is the correct one...they start doing an american country dance,,,lolz
