[There's not really much time to stop, but Lee certainly tries--after all, no evil mastermind would sit around outside eating lunch in the middle of their own illusion, right?! So he has to be an innocent! .....Or at least an illusion himself. Either way, not somebody he needs to trample. So Lee yelps in alarm and does his best to put on the brakes, dirt and grass spraying out behind him as he digs his heels in and skids the rest of the way, ending up folded over the picnic table hard enough to slam the wind right out of him. The table jolts, the lunch wobbles, and the landscape has a rather unattractive new set of furrows leading straight to the table..... but other than that, it looks like the only thing damaged is Lee's dignity.
For a moment, he only groans dazedly from the force of the impact, gasping for breath and remaining slumped where he is as he tries to regather his wits.]
