The little man in the hat flew across the room, under the force of Batman's rage. The laughter was as broken as his jaw, but the man became frenzied when Batman snatched away his top hat. "Ten shillings, six pence! Ten shillings, six pence! I do not own the hats, I merely sell them!"
As Batman's foot came down upon the hat, and a strangled cry came from the man, Batman growled, "Tell it to Saint Bruno." Hatter got the reference, eyes widening in sudden fear as the police arrived to drag him away, and Batman wasn't sure if he should be surprised or not. Saint Bruno - beheaded on October the 6th.
The girls were more difficult to deal with, and not only because they were painful to look at. Ten six year olds, arranged around a table prepared for tea, all wearing headbands connected to the Mad Hatters, enabling him to mind control them. The girls had begun to come out of their stupor when Batman had destroyed the top hat, and were just now regaining their memories of the last six months to two days, depending on how long they'd been missing.
The horror, trauma, sadness, was overwhelming, but while some shied away from Batman, others recognized him as a friend, and reached for him to take them to safety. With the help of the police, they were carried to an ambulance, and Batman cursed the world for letting people like Mad Hatter exist.
Then the call from Oracle came in, and a wave of exhaustion hit him like a tidal wave.
Ignoring it, as he always did, Batman responded with the first thing that came to mind.
"I'm on my way. Have we found Jason? Don't let him near Joker."
