I suspect that the magic bean that Rumple gave to Regina in return for being released from the prison cell was the same one that Blue gave to Bae.

Rumple might have refused to even contemplate travelling to a land without magic, so Bae possibly left home,  and sickened by the taint of magic, he left the bean behind. While on his travels he could have ended up being tempted by the call of Pan's pipe, as he was a 'lost boy'.

He clearly escaped Neverland (possibly using the trick with the candle and the half coconut shells to trap the shadow) but once home instead of reconciling with Rumple, he became a squire (and when he grew older a knight) and met / fell in love with Princess Emma.

After Baelfire's death, Rumple might have wanted to use the dark curse to travel to the Underworld in order to bring him back, using Regina's desire to send all her enemies quite literally to 'Hell' as a driving force.
