oh shit , thanks.I don't think Itachi was ever shown in a panel reading the tablet.
oh okay , thank you.He said he read the tablets in his fight with Sasuke, and he is also the one who told Sasuke to read the tablets, so he did read them. However, there is no actual panel that I can recall that shows him actually reading the tablets. The closest thing we got to that was when Hiruzen was praising his intelligence and we saw flashbacks of him as an 8 year old reading something, but it was never revealed what it was or where he was.
