Kishie can be predictable. Most people were perdicting that Kakashi got his sharingan from his friend Obito years before the kakashi gaiden was drawn.
He mentioned Obito once in the chuunin exam arc at the monument and people knew that is who he got his sharingan from.
I hope Tobi isnt Obito, but I wouldnt be sad by it or nothing. Tobi is still a fun character regardless.
Back to the spoiler pics. Do you think the thing or things that came out of Diedra explains why he has mouth in his hands. That creature has the same exact mouth as his hands.
That explosion is pretty massive. I wouldnt expect the Konoha troops to come there next chapter or anything though. Even though, this fight has lasted a few weeks in our time. It has only been 5-10 mins in manga time. Konoha was doing a perimeter of 1km from each other and they were moving in a perimeter one at a time. This fight could be 5 or more kilometers away, from the end point of the search circle.
