MIDORIMA IS THE ONLY SANE MAN IN HIS OWN MIND. Seriously. He's just thinking 'why are they all standing around talking and crying, that is a ghost, we should get away from it'.

And then of course everyone gets pissed at him on Kuroko's behalf. GHOST OR NOT, THAT IS AOMINE'S TETSU. And Kise's Kurokocchi! He'll leave when he wants to leave and you stop being so mean to him!

And then they run. Because angry ghost.

I like to imagine Midorima throws salt at Kuroko next time they meet.
