I hope that this Andrew-Summer storyline hits an end now... Having a fling with a stranger during Tasha's house party will not look great for Andrew, however (and hopefully) it puts an axe on this drama... therefore both of these characters should get new and maybe twisted storylines, involving crushes. From what I see Summer can't stand that someone is who doesn't have a ''real job'' and doesn't even want to be at uni, actually is there... even though it's her own boyfriend. Isn't she frustraded about having ''just'' a basic job at a local newspaper ? Andrew tries to get where he wants in his business and with some hoops he manages to do it. He has a strong commitment for his business while Summer is very iffish about starting off with organising online content for a local newspaper instead making it big as a journalist. I bet if Summer was having everything as she planned then no matter how bad Andrew was failing with his business she would be all cosy and supportive from the start for him.
Maybe I'm wrong but that's how I saw the recent developments between them two. I really hope it's coming to an end now. Or one of characters leave Neighbours as it happens really often.
