“About five meters ahead, Nico was swinging his black sword with one hand, holding the scepter of Diocletian aloft with the other. He kept shouting orders at the legionnaires, but they paid him no attention.

“Yeah, okay. But, Nico, you do choose how to live your life. You want to trust somebody? Maybe take a risk that I'm really your friend and I'll accept you. It's better than hiding.”
