"Come on, Tobirama. It's not every day Madara and I get to return to Konoha. Let me show him around."
Inside the Sealing Space, Hashirama held Tobirama by the shoulders and even gave his back a few light pounds, speaking in a slightly wheedling tone.
"Are you kidding? Do you realize that if anything goes wrong and he lashes out, Konoha could be gone?"
Tobirama had originally only come over to discuss some ideas about Flying Thunder God with Minato and help guide Naruto's next stage of training.
Naruto had a talent for space-time, but his studies so far had focused on taijutsu and ninjutsu, leaving him no time to learn Flying Thunder God.
Still, it was not much of a problem. Minato's presence could perfectly compensate for that shortcoming during battle.
But relying on someone else would not do in the long run, so Minato and Kushina had discussed it and invited Tobirama over as outside help to guide Naruto's research into the Flying Thunder God Formula together.
Except...
The moment Tobirama arrived today, Hashirama had latched onto him.
"Don't worry. I'll be with Madara. Nothing will go wrong."
Hashirama put on a pitiful expression, gazing tearfully at his cold-faced little brother as he pleaded.
"..."
It's precisely because it's you, big brother, that I'm worried!
When there was danger, Hashirama was the safest, most dependable person around.
But when there was no danger, Hashirama would automatically turn into the greatest danger himself.

(Kurama gave you a huge thumbs-up and threw a lump of chakra at Hashirama, who was always pestering him, to express his dislike.)
"Tobirama, even if you don't trust me, you should at least trust Naruto. I'll take him along."
Seeing the distrust all over Tobirama's face, Hashirama decisively called for backup.
