Urgh, if anyone's controlling in that relationship it's Bea. "No Ned, you're not allowed to stick up for me." "Don't bring me a flower." "We can't hang out now, maybe tomorrow if you're a good boy & behave exactly as I want you to..." She's way too much like hard work, I really don't know why he bothers with her. He can never get it right no matter what because she was in a bad relationship & she was on the streets & Bea, Bea, Bea. 
I think Gary's going to develop a crush on Dipi. She'll find out & explain she's not interested & it'll never be mentioned again, like Amy's crush on Toadie.
