In the case where Maki Harukawa (Maki-roll) has unknown-ly died in the bathhouse, everyone is now at the class trial as they stood in their individual stand, You were close to Gonta as a partner. He promised he will protect you and trust you.. but now he is being accused as a killer of Maki Harukawa.

"G-Gonta no do that! Gonta want everyone okay. So Gonta take all knives from kitchen!" said Gonta.. he doesn't seem to be happy, telling by his sad face hiding from everyone

but everyone seem to be ignoring his statement, arguing and babying the brute.. that they always thought Gonta is lying about it. Telling by the big fingerprint on the knife, and even on the victim's neck.

You were worried about that because he is cutting his fingers off out of his deep depression and sorrow...

(no Shuichi, the detective were in this scenario.. and all is just angst.)
