August probably hasn’t met Bae. He asks Gold, “Do I even look like him?” My hunch is the little he knows–and it is very little–came from stories he heard or read. If he really did know Bae, he would know useful details that he would have revealed to Gold to win his trust (even something as small as Bae’s mother’s name or the name of Bae’s best childhood friend would have been sufficient.) And I doubt if Bae would encourage anyone to con Rumple and break his heart. Bae’s a straightforward person. Besides, a con was an unnecessary risk. If August had said,” Bae sent me to you, and to prove that, he told me to say that when he was little his favorite toy was a stuffed lamb named Fuzzy”– just by being upright about it and showing he has inside info, August would’ve won Gold over. I think the only reason to try a con job is that August knows nada.
