How was chapter 631 done?
Here's how the NS moment went:
After Sakura realizes Minato is an Edo Tensei
Minato: Don't worry I'm an alley. Thank you for healing Naruto. Are you his girlfriend?
Naruto: Um... Hmm? Yup! I suppose you can say that....
Sakura instantly smacks his head
Sakura: Shut Your Trap!! Don'y waste you're energy talking.
As Minato observes the two.
Naruto: Oww! You're suppose to be healing me! I've suffered more damage now!
Sakura: I'll heal the extra damage too
Minato (thought): She reminds me a bit of Kushina.
Minato (laughing): ha ha Please be gentle with my son.
That's how the NS moment went down, is there anything else you'd want to know?
