Itachi was no expert in medical ninjutsu, and couldn't answer many of their questions as far as that was concerned.

"When I was an Academy student, the instructor thought that maybe... I'd end up as a mednin... And my chakra pool wasn't much better than yours is right now." He offered with a smile. "But while I had the chakra control, I had a far greater affinity for yin release... and no affinity at all for yang release. With my sharingan, genjutsu became an obvious focus after that."

That, and Fugaku probably would have been appalled at the idea of a medic as the head of a battle-focused clan. But Itachi wouldn't say that in front of the kids!

"Don't underestimate yourself. Any of you."
