Many things about this conversation:

Terezi is unfamiliar with the concept of pawn shops

Meenah is really good and angry fish puns

Either Meenah knows another person named Pyrope that looks like Terezi, or Pyrope is like a class name. I think the former

Meenah doesn’t even flinch when Terezi does say she is blind.

I think this is probably the favorite part of the conversation so far, and not just because of the puns.
