I liked her better than Dexter's other non-Rita love interests (namely Lilah and Lumen), but I don't particularly care for Dexter having these love interests in the first place, tbh, because he becomes boring with them. Still, I'm glad she's coming back, because it would have sucked if what we saw in the finale was the end of her arc. It would have seemed like a total waste, and now that she and Dex are officially over and she'll almost certainly be out for revenge, I might actually enjoy their storyline more.
