Ok, I doubt if this is Emma’s foster brother etc. Emma was a loner she traveled to OR, to AZ for prison and back to Boston where she started out as a baby. Dressing up is more like a date to me then meeting an old friend besides if it was an old friend don’t you think you would want her parents to meet him too?
Also, it looks like the guy comes up behind Emma so apparently Emma doesn’t know what this person really looks like that she is suppose to meet.
Could this guy be “Prince Naveen”, The Princess and the Frog…???
