Bart stood stalk still and blinked for a second as the kid started running towards the explosion.
"Oh. Oh I see." He said quietly, though a very slow (for him anyway) smirk/grin started to rise on his face until it exploded like a volcano, taking up his entire being, it seemed.
"So, you vish tu race, ya?" Bart said to no one in particular in a very strange half-Russian, half-Swedish, all-BAD accent before he mimed pulling goggles down over his eyes. He watch the kid get further and further away as he hunkered down and braced his feet back against the ground as if they were on runner's blocks, holding himself up with just three fingers of each hand on the ground. There was an imaginary gun shot, and suddenly Bart was up and breezing right up to Damian, his legs moving at super speed. He even turned around so he could run backwards and gave Damian a salute before turning back again to face the mess they were running into, though he did slow so that Damian could keep up with him.
