Going by main character, here are the plot threads that will have to be tied up in the second half of Season 6 (or at least should be tied up):

Emma:

- More about the Savior mythology

- Find out why Gideon is trying to kill her, and (assuming she doesn't die) how she avoids that outcome

- Find out about the sword that is going to "kill" her

Snow:

- Break the sleeping curse on her and David

David:

- Break the sleeping curse on him and Snow

- Find out what really happened to his father

Regina:

- Get closure with Robin's death via Wish Realm Robin

- Either defeat or reabsorb her Evil Queen half

Gold:

- Get back with Belle

- Figure out what happened with Gideon, and how to help him

- Resolve his issues with his mother, The Black Fairy

Belle:

- Get back with Gold

- Figure out what happened with Gideon, and how to help him

Hook:

- Not sure at this point

Zelena:

- Not sure at this point

Henry:

- Not sure at this point

Also, we know of four guest characters that will be somewhat important in upcoming episodes, here is what they have to resolve with them:

Aladdin:

- Be a Savior

- Get free from being a genie

- Get with Jasmine

- Probably more flashback backstory

Jasmine:

- Figure out what happened to Agrabah

- Get with Aladdin

- Probably more flashback backstory

Gideon:

- Get help from his parents

- Try to kill Emma (and probably fail)

- Find out what the Black Fairy did to him that made him rapidly age and want to kill Emma

Black Fairy:

- Resolve drama with Gold

- Show backstory of her and Blue, why she was banished, etc.

- Probably show backstory of her and Snow, where she gives Snow the dark fairy dust

- Show what she did to Gideon

While this looks like a lot of points, remember many points overlap, and could even connect. Like what happened to Agrabah could connect back to the Black Fairy, for example.
