Does Sasuke love itachi most? Like more than anyone else? More than his mom and dad?

[[ Sasuke does care for Itachi absolutely more than he does for any other person.

But one of the reasons he has such a strong tie for Itachi is that his parents died when Sasuke was young (obviously we all know this,) but Itachi stayed alive. 

Thus Itachi’s life means more to Sasuke emotionally– especially when Sasuke finds out the truth. Sasuke just never got the time to bond more with his parents, as they were also dealing with their own problems (Fugaku with the clan and rebellion, and Itachi; and Mikoto also wanting to help with the rebellion.)

I don’t think Sasuke would’ve bonded more to his parents as opposed to Itachi in a non-massacre scenario anyways, but it would be a less severe divide. 

This isn’t saying he doesn’t care for his Mother and Father. Of course he does– they’re his parents and it’d be amazing to have them back, it’s just his feelings for Itachi are at a severe level. ]]

His eyes close for a second, relishing the feel of rest. Kaasan had him run errands all day. Itachi is still too tiny to do much, speaking of which he’s still in charge of looking after him! Pushing himself up on his hands, he looks to his baby brother. Scooting over to him, he pokes the one year old’s tummy. “Itachi,” he calls, tilting his head.

Itachi calls back, even if his sounds are restricted to lone, weak vowels. He’s heard Sasuke’s name many times, but the ‘s’ still eludes him. It’s difficult, without teeth.

But he’s happy. Infront of his brother he’s more expressive, kicking his legs and reaching out for the hand that touched him.

That will fit in his mouth, won’t it? At least, the fingers should.
