I voted for Alex & Alex.
I like him. I can't help it. He's the person in there that's most like the 20-somethings that I know and I can completely identify with the awkwardness.
He hasn't been perfect, impossible when being filmed 24/7 over 8 weeks I would've thought, but I've found him less annoying than the others.
He seems to be a good friend, and it speaks volumes that he's so well liked in there. Even people like Ellie, who he had disagreements with, spoke quite highly of him.
I think I like Alexandra too, but she hasn't been there very long.
I like Laura too. I'm still disappointed Alex & Laura1 didn't get together, even as friends.
