This is the first appearance of dream or new Hook who later would be called "Nook" by Zelenas daughter Robin.
According to Jennifer Morrison and Colin O'Donoghue the scene when an older Hook tries to rescue Emma was hard for them to film because they kept cracking up. During one take Colin as Hook grabbed a chisel and fell because it was wet and slippery and according to him Jennifer found this so funny "I actually thought she was going to wet herself"
Dream Hook calls Emma Princess Enya. Its a joke because Enya has songs about water including one of her more famous songs Orinoco Flow which has a chorus of "sail away sail away sail away"
