Stefán Karl Stefánsson / Robbie Rotten - The man who saved Josuke when he was four

Robbie looks at the car, the driver is carrying a sick passenger. The driver stoods in fear after looking at the bruised Robbie, tempting him to stay away. Robbie then says "Your car stuck down there? And that kid is sick right? I'll push the car for you" as he throw his coat, his only possession on the car's back wheel. "Hurry up and step on the gas. Once you get moving, don't stop, just keep going… Or your tires will stuck in the snow again".
The driver acknowledges his directions and hit the gas as Robbie pushes the car. The sick passenger, who is revealed to be 4 year old Josuke sees Robbie's and his iconic hair on the car's mirror and smiles. The car's slowly moving and finally goes. As the car goes, Robbie pulls back his coat and strike a pose.
But after the car vanished from his vision's range, Robbie collapsed. He loses too much stamina as he unable to resist the cold. However, he never regret his actions, never knowing that he saved someone's life. He uses his last strength to move himself out of the road until he finally fell on his knees and dies.

After years of unsuccessful attempt of making the Lazy Town lazy, Robbie gives up and leave the place and his lair he was proud of for good. He also struggling against his internal illness which getting worse everyday.
He caught on a fight between juveniles and barely made it out. And a snowstorm kicks in. It's nearly hopeless for him, no telephone booth, no bus stop, nor a derelict building. He decided to give up at this point until he found a car driver struggling as it's wheels stuck on the snow and she has no hope to go until the snowstorm subsides.
