do you ever just have those days where you feel so happy and everything is going really well but then out of nowhere your mind decides to remind you neji’s dead and it’s just like:
It has always been used to create distance and followed by false promises.
Itachi himself acknowledged it.
When Itachi died for good, after Sasuke knew the truth, he did NOT poke his forehead. There was a lot of emphasis placed on this. Kishimoto made it look like Itachi was going to poke him but then he pushed their heads together, instead. The way he decided to drag out the process made you pay attention to Itachi’s movements and notice this difference. He made it as obvious as possible that the forehead poke was NOT something good and the goal should be to move beyond that point.
That being said…
Sasuke creates distance between himself and his “family”. He cannot keep his promises to them. They see it as positive because they don’t understand what it represents. There’s no reason that Sasuke would have taken that and completely changed the meaning, it’s used for the same reason. It’s not malicious but it shouldn’t be romanticized. Calling this his “ultimate expression of love” is just plain idiotic.
Sorry to burst your bubble but Naruto never reacted to Sasuke being in danger the way he reacted to Hinata. In the Pein arc and in the Last he looked like he'd lost his effin world. Your ship can't top that.
