Hint 2
Most of their conversation is fairly pointless -- Rosa does not either waddle like a duck! -- but you do find out that they use Bmail, the same email service Rosa uses.
Hint 3

Hint 4
Go back to the office, leave, and send Joey in to eavesdrop. Go stand over by Paul especially. Remember Joey's interference with airborne radio signals? We're going to use that to our advantage.
