no one really speaks about shauna and the reason shes dating melissa besides the fact she wants power (and also because she cant have jackie anymore) but like. i think another very big reason is that she sees herself in melissa. like melissa is a follower, a sheep, a lapdog maybe, and after we learn that shauna was really following in jackies footsteps in season one, its easy to see that melissa is a very good depiction of shauna before the crash.
i think shauna is trying to take melissa's impressionability and manipulate that into how she wants herself to be. she's taking out her anger from her actions in season one out on someone else, almost as a way to 'punish' herself, even if she's not the one necessarily getting punished.
