After leaving when you were 4 years old, you return to Kattegat as an adult 20 years later, you were worried that nobody would remember you but to your surprise you're met with a small gathering of people who are all glad to see you, you think fondly on your childhood friend Ragnar, you used to play and fight together all the time, you'd developed a habit of flicking him in the forehead. You were still on the shore when murmurs and chatter began. You looked up and saw Ragnar approaching you from the town, curiosity and disbelief in his eyes.

"Why do I recognise you?" he asked.

You smiled, beckoning him closer, as he leaned down you flicked him in the forehead, just like you always used to do. It took a second, but recognition slowly took over his features.
