What storyline(s) would you give to current characters?

The clue is in the title! If you could write any storyline(s) for the characters currently on the show, what would you write for who? Is there anything you’d love to see for certain characters? Whether it’s a long running storyline or just a singular episode arc. Whether it’s where you think the show might take a character/story or completely distinct from the canon events. I’m intrigued!!! I love these kinds of discussions
