Batman had no idea where he was. It seemed to be an abandoned building, somewhat familiar, but he couldn't place it. How did I get here?
He looked where the Doctor was. Nothing, just a few dusty crates. In fact, as he looked around, most of the interior was cluttered with dusty crates. Batman wandered around, looking for an exit, all the while trying to figure out how he got here in the first place.
He eventually found an exit, unlocked it, then opened it to the outdoors. Outside the building he was in, it was evening, and the moonlight shone on a trashy street. It almost looked familiar to him, like what Gotham used to be when he was young.
After a quick scan of his surroundings, he ventured out. Once he had crossed the street, he turned to the building of which he came out from. He couldn't believe it. It was the museum, looking like as it did before Wayne Industries funded a restoration and re-opening. It was like looking into the past. But... how?

The Doctor kept his eyes on the angel, not daring to blink. "How'd you get here?" He asked the statue. The statue, of course, didn't respond.
The Doctor, still watching the angel, slowly pulled out his sonic screwdriver and scanned the angel. Then, after the scan was complete, he slowly moved his left hand until he touched the right arm of the angel. Just then, the entire marble arm cracked off the angel and smashed onto the floor. This wasn't good. Not good at all.
He scanned the kryptonite with his sonic, which said that he only needed a small piece. He broke off two and ran for the exit. As quickly as he could, he crossed the street, into the alleyway, then entered his TARDIS.
He ran to the open floor grate next to his console and rummaged through the wiring until he found the correct wire, attached it to one of the kryptonite pieces and then placed it back with the rest of the wires. Standing up, he closed the grate and went to the console. He took a deep breath, then started up the TARDIS.
It worked. The TARDIS hummed with life, the lights came on, and she wanted to go. The Doctor typed on the keyboard then looked at the screen. If he was correct, the angel sent Batman 24 years to the past. This wasn't good at all. He ran to the other side of the console and pulled the lever, and entered the Time Vortex.

Batman walked down the street to where he parked his Batmobile, only to find it gone. As he walked further down from the street, he saw it. He couldn't believe his eyes. It was as if he was sent back in time. Only 2 months of crime fighting and he's already part of science fiction. In front of him, just a block away, was the theater, exterior lights shining, with the sign saying "Now Playing: Zorro". And the date. THE date. 24 years ago. The date that will forever haunt him.
He was so mesmerized, he didn't see the angel statue to his left, smiling.

"C'mon, c'mon!" The doctor was having trouble navigating the TARDIS to 1973. There seemed to be time interference, most likely a paradox at work, which is what the Doctor feared. This is a fixed point in time in this world. It mustn't be changed! The Doctor pushed more buttons and pulled more levers. Nothing was cooperating. Maybe he could go back to a bit earlier...

Batman was across the street of the alleyway where his parents were shot. He was waiting for his 8-year old self to leap through the theater doors. Behind him, there was a sudden gust of wind, a grinding noise, then a thud. Batman turned around to find a blue telephone box that wasn't there earlier.
The door swung open and out popped the Doctor. "Stop what you're doing!"
Batman looked at him questioningly. "How did you-?"
"Not now Bruce!"
Batman silenced when the Doctor used his real name.
The Doctor drew a long breath. "I know what you're thinking about doing, but you can't do it."
"Yes, I can."
"No, you can't! It doesn't work like that! There are fixed points in time that mustn't be changed, ever!"
"And you would know because...?"
"I'm a Time Lord. The last. Name's the Doctor. I travel through time and space in my TARDIS."
"Your what?"
"TARDIS. T-A-R-D-I-S. Time And Relative Dimensions In Space."
Batman knew deep down inside that this man ought to be crazy, but everything he said made sense, in a way. He had another question. "How did I get here without a time machine?"
"Good question." Said the Doctor as he pulled out his sonic screwdriver. He forgot to do it slowly and Batman almost knocked it out of the Doctor's hand out of instinct. "Whoa! Easy. It's a sonic screwdriver. It only makes sounds and does medical scans. It's okay." He paused for a moment. "Trust me."
Batman nodded in approval as the Doctor scanned him. "You're overflowing with time energy."
"What?"
"Time energy. Wibbliness. It's hard to explain, but long story short, you came here because you were touched by an angel."
Nothing the Time Lord said made any sense to the Dark Knight.
The Doctor explained everything as fast as he could. "You were touched by an angel, a Weeping Angel. They're an alien race that feed on time energy. They touch you, and you go back 50, 100, or even 300 years, but this situation is different. Instead of taking away your time energy, a Weeping Angel gave you the last of it's own, killing itself and sending you to a certain time with enough time energy to feed an army of them. But they're not stopping there. They want even more time energy. An extreme amount of wibbliness. And the only way to get that much time energy is by sending you back in time and cause a paradox by stopping the death of your parents. A fixed point in time that MUST NEVER be touched."
Batman understood most of the concept, the next part was believing.
The Doctor looked at his watch. It was 10:43pm.

Eight-year old Bruce jumped through the theater exit, swinging an imaginary sword against an imaginary foe. "Zorro is the best movie yet!"
Martha and Thomas Wayne walked out of the theater shortly after. "Come on Bruce." Said Thomas to his son. "Let's go find Alfred."
"Okay!"
They walked down the road and turned into an alleyway.

Screw it. Thought Batman. He turned around and headed into the alleyway. The ran after him and grabbed Batman's cape, only to be kicked in the gut by the vigilante. Lying on the ground, he used his sonic on his TARDIS, giving it specific directions as it faded away, then materialized around him.

Batman reached the alleyway when he suddenly heard some sort of whooshing and groaning, and the TARDIS materialized around him. He looked around, completely unsure of where he was, until the Doctor materialszed in front of him.
"What's going on?"
The Doctor painfully got up and went towards the console. "I'm stopping you. I'm doing your job. I'm saving you and the world!" He pushed buttons and twisted knobs. Half of them didn't really do anything, but if the Doctor was honest with himself, he loved showing off.
The Doctor pulled the lever and they were off! Until... THUMP! The TARDIS bounced off of something big. The Doctor pulled the lever down even further and the crash was heavier. He ran to the console screen. "No!" He shouted.
Batman, still trying to gather what had happened, turned towards the Doctor. "What is it?"
"It's just a hypothesis, but I've never seen this happen before."
"What is it Doctor?"
"It's the angels. They're generating time energy and the TARDIS is overflowing with it. They're shoving ALL their energy down her throat!"
"But what does that mean?"
"We can't pass the time field. We keep bouncing off! We're stuck here! We're a fixed part of time!"
