I'm a bit confused with "then." Could you give some more examples like "then" here?

"Then" here is used as a suggestion. "Paper then?" is like saying, "how about paper?", or "in that case, is there paper?". Here's a few more examples of this: Ex: A: I don't have class today. B: Let's go to the beach then? A: We know each other from school. B: So, you're friends then?
