Justin looked up from his chips at the sound of the opening door, and felt a wash of relief as he saw it was Hannah. He moved his hand to wave her over... but she simply looked straight ahead, intent on her destination, which was apparently her flat upstairs.
He sighed. Her mind was obviously on something. She couldn't have seen something last night too... could she? No, that would be too weird, more than one person...
He shook his head and rose from the table, abandoning his leftover chips to follow Hannah upstairs.
Once there, he knocked on the door, knowing she would answer this time. If she didn't, he'd have to knock the door down, or... something.
