César sees nothing but an ordinary young man. Who just went past him as he himself takes a run on the track. Wow, he's pretty fast.

And shortly later, he gets passed again. Wait? Shouldn't he be tired? Then eventually a third time, and César is so distracted by this that he just... slows to a halt and watches the guy.

He's just. Going to walk off the track and wait until the guy is done running to talk to him. Because he doesn't want to interrupt him. César knows what it's like to be in The Zone.

"You've probably heard this a lot, but, wow, you're really fast."
