Batman probably reacted to Bart's sudden appearance better, and he'd had less warning. Barry probably hadn't sent him a text message. But of course, he didn't need to. Batman was "The World's Greatest Dectective" and more wired, paranoid and controlling than Big Brother in 1984. When the redheaded teenage, fast-talking whirlwind that was Bart burst on the scene of his front hall, GA's immediate response was,
"Holy hell, it's Kid Flash!" Then, "Barry, he's like a freaking mini-you! With red hair. That's..." he trailed off, unwilling to say the rest in front of the kid.
