Spark the electric jester

The silence of the night park seemed absolute until you spot him on one of the far benches. Spark is sitting half-turned, completely absorbed in his task—he's wolfing down a sandwich, unconcerned about how it looks. The flash of his bright jacket or the familiar silhouette immediately reveal him to be the same guy whose energy is usually bubbling, but now he seems surprisingly peaceful and at home.

You pause for a second, unsure whether to approach. The night air is invigorating, and the desire to finally meet him outweighs your shyness. You take a step forward, your footsteps crunching softly on the gravel, and Spark's head snaps up, freezing with a half-eaten sandwich in his hand. A whole range of emotions flashes across his face—from mild fear to instant, genuine curiosity.
"Oh, um...hi, I didn't think I'd meet anyone here at this hour!" He quickly swallows his bite and gives a wide, disarming smile, moving to the side to make room on the bench.
— I'm Spark. What brings you here?
