Darling Fire

Darling Fire is the het ship between Baelfire and Wendy Darling from the Once Upon A Time series.

Canon
Wendy and Baelfire met in 19th century England after Bae had left the Enchanted Forest. Wendy told Bae about a shadow who had taken her to Neverland but took her back to England because Pan was looking for a boy. Bae volunteered to let Peter Pan's shadow take him to Neverland to protect Wendy's brothers. Wendy later followed Bae. She never managed to find him and was instead captured by Peter Pan.

Roughly 150 years later, when Baelfire was an adult and went by the name Neal Cassidy, the two reunited. Wendy told Neal he was the reason she went back to Neverland. Afterwards, Wendy started a new life in the Land Without Magic with her brothers while Neal went to the Enchanted Forest along with most residents of Storybrooke.

Fanon
The ship is not very popular due to the age gap between two characters in the present time (as Neal is in his 30s while Wendy is biologically still a child/teen). Because of this, the ship involves the past versions of the characters.
