It was the look on Itachi's face that really told him the younger man's thoughts, and it was all he could do not to pout. In fact, he probably did a fair sight better than he had intended to in hiding his notice of it, waiting until they were on their way to the seal point before directly looking at him...

And then waiting until they were on the other side before speaking.

"If I didn't know better I'd think you didn't like me anymore Itachi."
