Sunday's all-new episode is titled Second Star to the Right and ETonline scored this in-depth featurette where Eddy and Adam address this central question: Who Is Baelfire?

Of course we know Baelfire is Rumple's son and grew up to be Neal, Emma's ex and Henry's father -- but as you can see from this video, fans may also come to call him another name ... Peter Pan!

Once Upon A Time airs Sundays at 8 p.m. on ABC.
