Great. She doesn't speak Italian.
But she was yelling some heavy words. Granted, Ben didn't speak Italian either but it was essentially the same thing as Spanish. She looked English, or American. Oh wait, they teach Spanish in schools there. Maybe she knows some broken? Benjamin uncrossed his arms and took a more friendly stance. He even smiled. After sidestepping the group he found himself next to Artemis. He placed a hand on her shoulder and pointed to her punctually, asking, "Amigo, o enemigo?" Friend or foe. He was asking her if she was the assassin, which a real assassin wouldn't answer truthfully but at the very least maybe he could resolve some tension. And hopefully, she didn't live under a rock and could extrapolate what he was asking. Besides, she looked quite the opposite of intimidating. Unless she was really into reverse psychology then she was probably a safe bet. If she was Mafia and she didn't want them dead, it would be in his best interest to be friendly, anyways. She might be able to shed light on the world that Sonya had, to date, explained nothing about.
