The medication completely gone from his system, Nico suffers and goes berserk.
Wanting his medicine, Nico attacks Hachiman.
Upa and Liang is surprised to see Nico in that state.
Then, the traitor, Qi, appears.
Qi understands medications can turn into poison if they’re not handled properly.
He remembers the days when Hachiman used to treat him like a tool along with Upa and Liang.
but I brought the keys to 
the cell and handcuffs...
...لكنّي أحضرت مفاتيح الزّنزانة والأصفاد
aber ich hab Kerker- und
Handschellen-Schlüssel dabei!
mais j’ai pu leur piquer
le passe-partout !
ma ho portato le chiavi
della cella e delle manette...
mas eu trouxe as chaves
para a cela e as algemas...
но я принёс ключи
от камеры и наручников...
