I'd love to see more Diana/Christie! I know that they are a couple, but they're a lesbian canon couple!! And, even though they are not very important, I would want to see them interacting with El and Sara.

Also as sahiya said, I'd like to see more El & Sara. They are really similar and if Neal and Sara do end up in a stable relationship (which is entirely possible in fanfic!!!), they would have a lot of things in common to discuss! I may need to write this now!

And lastly, I would love to see El & June. They're so different, but yet, I think they would get along. I could see Moz dragging them both off somewhere.
