On-Screen Notes

 * True love's kiss will not break a Dark One's curse if the Dark One likes the power and does not want to give it up. When the afflicted wants it, it is no longer a curse. Nor will true love's kiss work if both people involved are Dark Ones.
 * According to Cora, when The Dark One is killed without the dagger, he/she will expel the powers of the Darkness.
 * Dark Ones don't need sleep as the power of the Darkness keeps them energized. Dark Ones such as Rumplestiltskin and Emma Swan developed hobbies to pass the time instead; Rumplestiltskin spun straw into gold and Emma made dreamcatchers.
 * The waterfall in the pocket dimension inside the Vault of the Dark One is liquid darkness.
 * All Dark Ones find it irresistible to make deals.
 * The Darkness is immortal. This is a result of Nimue drinking the waters of the Holy Grail.
 * The Darkness appears in the title card for "Birth". The hooded figures of all Dark Ones prior to Rumplestiltskin appear in the title card for "Swan Song".

Appearances

 * Dark One Rumplestiltskin appears in Henry's storybook in "Dreamcatcher".
