Idea: Sam and Cas teaching Jack enochian. Jacks half angel and I feel like he deserves to learn more about that part of himself than he did in canon.
Jack has "classes" every day, where Sam and Cas teach him about his angel side. They start teaching him enochian, ( though it is a very hard language to understand, and took Sam hundreds of years to become fluent.) they start teaching him enochian, and Cas also tells about him about history of the angels. Sometimes they even have Gabriel come down and tell jack stories about the archangels. (They mainly stay away from the topic of Lucifer though.) Jack gets upset when Gabriel tells him about when he put Sam in the time loops (Sam just sighs, saying it's water under the bridge), but jack does think it's funny how Gabriel turned Sam into the impala briefly (Cas is surprised about that, he didn't know that that happened)
Jack enjoys learning about his angel side, and is glad that Sam and Cas will teach him!
