Jesse was miles ahead of him, but Bart caught up to her just south of Virginia and waved as he ran up alongside her.
"JESSE! What are you doing out here?! And in your costume! Are you back? Are you really really back?!" Bart shouted with excitement, looking like he might start jumping up and down at any minute.
