Titus Welliver (Man in Black) broke two of his toes while filming the scene where Jacob is forcefully taking him to The Source.
This episode is set in the earliest time of the Series, reaching back up to about two millennia.
This is the third of only three episodes not to feature a secondary storyline. The first two were Season 2's "The Other 48 Days" and Season 5's "316".
Claudia's abdomen remained large even after delivering the twins. While afterbirth would still contribute to girth, the volume of two newborns would have significantly reduced the size of her womb.
When the skeletons were first discovered in "House of the Rising Sun" (shown in this episode as flashback) they were separated and not lying side-by-side, as we see Jacob placing the bodies in this episode. This was first seen in Lighthouse.
When the Man in Black is throwing sticks for the Senet game with Jacob, the sticks shift position throughout the shots.
When the young Man in Black is talking to his mother about the game he found on the beach, someone can be seen reflected in his eye.
When the young Man in Black sits at the beach as "mother" approaches we see a sea turtle on the beach in front of him. When the camera pulls out, the turtle is nowhere to be found.
The knife that the Man in Black carries in the episode is most likely the same knife that he gives Richard to kill Jacob, and that Dogen gives to Sayid to kill the Man in Black.
Claudia is now the third woman that we know of who has come to the island pregnant and near term, delivered the baby on island, and then had the baby taken and raised by another - the other two being Claire and Danielle Rousseau.
When the Man in Black is born, his mother does not name him, saying "I only chose one name." Throughout the rest of the episode, both his adoptive mother and Jacob always refer to him with pet names ("My Love", "Brother") and personal pronouns.
Young Man in Black: Jacob told you what I found.
Mother: Of course he did. Jacob doesn't know how to lie. He's not like you.
Young Man in Black: Why? What am I like?
Young Man in Black: Can I keep the game?
Mother: Of course you can. That's why I left it for you.
Young Man in Black: It came from you?
Mother: Of course it did. Where else would it come from?
Young Man in Black: From somewhere else. Across the sea.
Mother: There is nowhere else. The island is all there is.
A joke title among the producers, according to Damon and Carlton on the offical podcast, was "I'll Just Sit Here in the Dark".

This is a Jacob & The Man In Black-centric episode.
Of all the guest characters that have had their own episode, Jacob becomes the only one to have 2 centric episodes.
The Last Supper/Communion: When Mother makes Jacob the guardian of the Island, she shares with him red wine and tells him that they are now one (in communion if you will). In Roman Catholic tradition red wine is used by the Priest to celebrate Christ's last meal with his apostles as he used the wine to symbolically join them with him. Also the Catholic Eucharistic Prayer mentions "This is the cup of my blood, take this and drink, so that sins may be forgiven."
Senet: The Man in Black finds a Senet board and pieces on the beach and claims to know how to play without ever having played it before. The Senet dates back to predynastic and ancient Egypt and may be the oldest board game in the world. Senet boards were often placed in the grave alongside other useful objects for the dangerous journey through the afterlife.
