With Andrew now heading in a new direction following the break-up, Digital Spy recently caught up with Jordan Smith - who plays the character - to hear his thoughts on the storyline.
Smith, reflecting on Andrew and Summer's issues, told us: "I think the reason they don't work is that they're very young… Andrew's not the best at morals, so he's good at just going for what he wants. If he wants something, he's going to get it. He doesn't care who he cuts down, it's the end result that matters - whereas Summer's all about how you do something.
"It's very hard to be told as an 18-year-old that what you're doing is wrong - from both sides. So I think that's the downfall of the two of them."
He said: "[There's been] a definite, massive change. When you change the head of anything, it's always going to have a knock-on effect, and these guys have come in and pretty much taken over in the best possible way.
"They look out for you - even though they're running an entire show of 500 people, they've got all the time in the world to talk to you. They've brought a new life into it, I guess… It's a really good change that's going on at the moment."
