That faction name is a mouthful, but other things he says makes sense. She didn't know just how far Earth had progressed when it came to dealing with other species. Some of what he says is actually familiar to her.

"I know of the Chitauri." When he doesn't finish speaking of Avengers, she has to wonder what that was about but doesn't press upon it. Probably more of what he said. People working to protect the Earth from others. If the Chitauri were involved, Gamora already knew what that meant.

"If we have common enemies, perhaps they are the ones responsible for our being here."
