I really wanted to see some more Laura scenes. If it leads to a threesome with laura/amy or laura/sarah, even better.
And out of all the non-family storylines, I seriously want to see some fleshed out scenes with Chloe, or in a perfect world, a full storyline with her. Hell, I'd take just being able to hire her for her services at night, seeing as she's a prostitute.
I have to admit I don't really care about Beth or Turner. We've already got the bitchy classmate with Daisy, and Taylor filled the teacher role well enough. If we're getting another teacher, I'd rather it be the principal.
