The Iga sisters have very expressive eyes. It's very nearly the only part of them visible- so I suppose it makes sense. The Uchiha's eyes are just as expressive, but it's strange- for all that they show their faces, it's the eyes that allow the most insight into whatever's going on in their heads.
Maybe all that close personal contact they've had over the past two years has made the two clans really close? Eugh.
Troublesome. I'm not looking forwards to the hike up to the Iga Fort to talk one of them into dragging their ram back onto their lands- but Yoshino was very clear. Ugh.
So troublesome.
