Just Alpha!Jessica and Omega!Matt being an awesome snarky couple. They fight bad guys as well as people who think their partner is, respectively, a "cold hard b. incapable of human emotions appart from anger" or "a useless in a fight (doubly because of his blindness) good only for one thing" omega. Matt uses his lawyer skills and Jessica her sharp (and foul) tongue to shut down anyone that dare talk like that about the other. While at first they pretend to be annoyed at one another "I can fight my battles, thanks", in the end they're both touched by the nice things that their partner said about them in those circumstances.

+ they find the way the other talk there, fancy lawyer!talk, and at least one-swear-word-by-sentence!talk, very attractive
++ alpha!women and omega!men are rare, so when people start being douches to them upon learning that Jessica is the alpha and Matt the omega and that they are a couple, they get the double wammy.
+++ they're still snarky/sarcastic towards one another but never mean, they know each other limits
