Just a little tidbit more.

Robin sat quietly before the computer monitor deep in thought as he searched for more clues on the Titans' current case. It had been agreed he'd stay confined to the Tower while Joker remained on the loose. Not an easy decision to come to with Robin's own reasonable protests presented to the team, but the adults were very adamant about it, so he had finally agreed to remain there.
Mostly it had been a quiet night, with the Teen Titans out patrolling the city watching the streets, and Robin monitoring the media and net traffic for anything suspicious, but then Impulse had run across a clue to the Shoelace Murders, managing to prevent one killing, but the murderer still escaped. Robin had immediately gotten all the details possible from the speedy kid before pouring over all the details possible of the case and running all sorts of checks and cross-checks that happened to pop into his mind. He felt extremely close to fitting the final piece of the puzzle into place. In fact, Tim could practically feel it on the tip of his mind and would have had it if a quiet noise behind him hadn't of distracted him last second.
"Kon?" Robin called out turning towards the dark room. There was nothing there. Eyes narrowed dangerously, Tim stood silently and stalked to the open door and peered cautiously into the empty hallway. Superboy should have been around there somewhere. "Anyone there?" he tried once more.
Still no answer.
Robin started to creep further forward when the tiniest of giggles escaped from above him. Jerking his head up he spotted the dreaded clown, as the giggle became a maniacal laugh. The Joker dropped down from his perch just barely missing the Boy Wonder.
"Ha Ha, I caught a bird in it's nest!" the Joker chortled. "How's the family doing, Boy Blunder?"
Growling Tim prepared to defend himself as he tried to control his boiling rage, "What do you want, Joker?"
That awful grin spread itself across the mad clown's face, "The exterminator's here to deal with a bad infestation of flying mice! I just need to pick up the cheese to lure the mouse to the trap." Joker stepped forward swinging his cane at the spot Robin's head had just occupied, but his other hand was ready with the gas gun—straight into Robin's face.
