"What does that mean? For... for both of you? Serving someone like that?"

Maeve has no idea what this person -- Emperor, God, whatever -- was like. Maybe he was kind or maybe he was a shit, but either way, serving someone doesn't exactly sound like it's a good time. She can't understand wanting that, but she's trying to be openminded and remind herself that her life and Gideon's life have been very, very different.
