A/N: Various short plot ideas that popped into my head. Not really serious sometimes. No slash or romance period. Just brother/sister/parental stuff.
Don't Mess with Robin
Tim had been patrolling Gotham on his own since Bruce was on a League mission. Nothing major, it was just that it required Batman's expertise at stealth. Tim was sitting on a rooftop, when something stung him. He realized that it was a tranq dart and thought, "Great, Bats will have my head for not being more observant. Better push the button before blacking out." Robin knew that it took time for a dart to take effect, not instantly like in the movies.
The signal was transmitted to the Batman and the other main Justice Leaguers. They quickly finished up what they were doing, left clean up for the police and hightailed it for the signal.
Tim woke up in a dank room with some random bad guy(let's call him John Smith, don't want to be specific) standing in front of him. John was going on with the "I'm going to kill you and do other evil acts" speech. Robin said, "Boy am I sorry for you."
John sputtered, "Me! You're the one tied up at my mercy!" Robin replied, "I'm with Batman, and you don't want to mess with an angry Bats, or with the rest of the JL for that matter." John sneered, "There is no way they will find you and get here in time!"
Tim whispered, "4…3…2…1…yep right on schedule!" For at that moment, the seven members of the Justice league came crashing through the wall. Robin muttered, "Still can't find the door can you? " Batman was giving his really fierce bat glare. Superman was giving the heat vision starting up glare. The rest of the league was giving their own version of the "you are so cooked meat" glare. John wet his pants of course. Tim just said, "Told you so. Don't kidnap anyone affiliated with the League, especially not one of the Bat's kids."
The rest can be left to the reader's imagination. It's the Justice league, they are not going to kill him, but they might make him think they will. Psychological torture leaves no visible scars.
