I wonder if Sasuke knows of Naruto's Sage mode? since they've been "frienemies" for a few years now I don't know (or don't remember) if Sasuke is aware of
Naruto's development (how he mastered Sage mode) and if Naruto is aware of Sasuke's EMS!!
was Sasuke jealous? Was Naruto aware that Sasuke has Itachi's Eyes? and when Naruto is in Bijuu or Sage mode can he feel Itachi's power within Sasuke?
(here is another question for the fun of it)
If you had to choose between Naruto's Sage mode or Sasuke's EMS which would you choose and which would you consider to be more powerful????
I would choose Sage mode since it enhances the body on many levels! but I consider EMS more powerful.
