[X] "Why do you want to stay Nagisa? Is there is someone you know trapped here?" If that's the case, try to reassure here that you will take care of rescuing them, but that she needs to get to safety.
"Why do you wanna stay, Nagisa?" You ask her calmly, "Is there someone else trapped here?"
"Maybe... If Mama's here, Nagisa has to find her...!" Nagisa says, the fear in her voice slowly being replaced by determination.
"Your mother?" Homura asks. "Why would she be here?"
Nagisa was about to speak, until you heard a familiar voice from behind you. "Ah, Yumi, Homura!" Mami greets you warmly. She looks at the Angel, and freezes. "Is that...?"
"Indeed. I am a humble servant of God." The Angel answers. "Together, we shall vanquish this supposed 'Witch'!"
"Um, about Nagisa..." You say, but no one seems to be listening.
"So, God is real?" Mami asks.
"Of course God is real! The Lord made you in his image, and fought to secure your future! Is this world not privy to His teachings?"
"Ah, I meant no offence! I just-"
"One thing at a time, Mami." Homura gives a tired look. "Please."
"So, about Nagisa..." You say, louder.
"O-of course." The Angel says. "We meet escort the child to safety."
"But...!" Nagisa begins, but you put your hand on her head.
"We'll save her if she's here, kid. But you gotta get out of here. We can't fight and defend you."
Nagisa is silent for a moment. "...Okay." She relents.
"I'll lead her out of the Barrier!" Mami says, taking Nagisa's hand. "Come along. Will you four be alright without me?"
