This chapter leads me to believe that Naruto is in fact related to the 4th somehow (most likely father and son). That old thoery seems much more logical now and the sharingan seems to be greatly influenced by ones emotions.

Also I don't see any random power ups...
Nine tail doesn't want to die and Sasuke is developing. Sigh why is he so stupid? Why doesn't he realize his sharingan just developed because he isn't using his stupid curse.
