"So, who is this Alexandra?" Darren asked just as they were inside Hugo's car. Hugo is driving the car and they are currently on the way somewhere that will lead them to where Alexandra is.
Darren didn't go to the company today and it was Hugo who spoke to his parents. They were actually very surprise to see Hugo again and welcomed him into the house. Something that Darren didn't appreciate. A man like him shouldn't be accepted to go into their home ever again.
His parents asked him when Hugo told them he's here to fetch Darren to go somewhere. And even when he wouldn't like to, it was Hugo who decided to tell the truth.
That his twin brother is missing and he needs to find him.
