I'd like to see Finn back. I don't understand why some people have been claiming Alicia and Elfman should jump into bed because they being together are "hot". Even if we count him sharing a victorious kiss with Alicia and then being coy as "hot" (which I seriously doubt), we can't ignore his bland character depicted so far.
To me, Elfman is a total stranger, and we know nothing about him, so if Alicia needs a fling he might work, but be in a real relationship for a complex character like Alicia? It doesn't make any sense to throw Alicia to him all of a sudden.
