Yes this is interesting. Takes off right where the other one left off. Part 2

Double Take

"Who are you?"

"I'm Robin." There was a slight amusement in his voice.

"That's hardly an explanation," Kaldur stated, glaring slightly as he came to the new boy wonder.

"Time travel. Can't really explain who I am. Have to find out the hard way." 'Robin' gave Kaldur a brief glance before going back to his typing. "Besides, I don't know who you are either. But if Robin here trusts you, I can too. Finally! I'm in."

Instantly on the boy's screen was a series of complex computer codes. Robin couldn't help but stare at it in disbelief. He never saw codes like this, and apparently neither had this 'Robin'. He twisted his lips in thought, but wasn't discouraged. Rather it looked like he was getting excited.

"How can any of us trust you if you don't tell us the truth?" Kaldur tightened the grip on his weapon.

'Robin' stopped for a moment, raising an eyebrow. Slowly he sighed, then put his hand on his utility belt. Everyone but the younger speedster tensed. Wally was watching that kid, a slight panic on his face. He hadn't missed Blue Bird calling the kid Flash's cousin.

No one had to worry though. All the 'Robin' did was reach into one pocket and tossed its contents to Robin. The boy wonder caught it and gaped at what it was. A small bat insignia, possibly a listening device the others surmised. The other 'Robin' went back to typing, not even the slightest bit fazed by the boy's reaction. "Do I need to give you some kind of personal key phrase for you to trust me? I could embarrass you in front of your friends, or give a detail on Batman you'd rather keep hidden."

"No need." Robin closed his hand then came closer to his doppelganger, passing the thing back to him. "Why am I not Robin?"

'Robin' shrugged as he put it away. "You grew up."

Robin glared. "Why are you Robin?"

"Batman needs a Robin." His hand slowed a fraction as he explained. "He needs someone by his side in the field to keep him sane. You know he can be pretty… extreme… when someone's not keeping him in line."

Everyone looked at Robin for a moment, and even he looked taken back. Batman… needed him? 'Robin' continued.

"And since you grew up, he couldn't keep you there. He tried solo a few times, but…" He hesitated. There was something dark, something bad he was remembering, and he couldn't share it. Worry started to fill Robin's face, but the other one shook his head. "I volunteered. About a year… no, two years ago. Yeah, and it's been hard. I'm not that great of an acrobat compared to you. I'm no boy wonder, just a teen wonder who figured it all out."

He gave Robin a grin, then went back to typing. "Besides, he always preferred working with you. After a while, you come by and visit a lot and… well… we're pretty close."

"Pretty close what?" Impulse asked, now leaning over 'Robin's' back, looking at his computer screen. "What's that? Some game? Can I play?"

"Get off Imp!" 'Robin' rolled the young speedster off his back, annoyed at him.

"Ah come on Rob!" Impulse whined. "I'm bored! We've been here for hours!"

"It's been 15 minutes."

He pouted childishly. "Feels like hours."

'Robin' rolled his eyes and went back to work. "Don't mind him. He's actually three."

"What?" Everyone gaped. Wally dashed over, unable to take being silent for another second. "What the heck is going on here? How do I have a three year old cousin who looks Rob's age?"

Impulse shrugged. "Hyperactive metabolism since birth. Grew up way too fast. Grandma took me from the 30th century to here-ish to save my life. Flash saved me."

"Imp," 'Robin' warned, "they said not to screw up the time stream. Clam it."

"How are you from the 30th century and my cousin?" The red haired speedster couldn't understand it, and wasn't going to listen to this imposter's orders. "And how am I the Flash? What happened to—"

Recognized – Flash 04

Everyone looked up at the Zeta-tube and the fourth speedster they've seen that day. Flash grinned at them. "Hey kiddos! Ready for a crash course in—"

"Grandpa!" Impulse launched himself at the scarlet speedster, wrapping his arms around him in a second into a monkey hug. Flash topped over from the kid's momentum, floored in more ways than one by him.

"What the…"

"Huh," 'Robin' mumbled, interested at the sight. "Flash number two. Always wondered what he was like."

"What's going on here?" Flash gaped at the kid on top of him, not sure if he should be hugging back.

"Spoilers!" the second bird chimed as he went back to his task.

"I'm your grandson!" Impulse continued, still grinning from ear to ear while nuzzling Flash's chest. "I've always wanted to meet you! I've seen all the photos, videos, games, disks, statues and everything! Grandma would tell me everything about you and Dad and Aunt Dawn and—"

"Get off him!" Wally was at their side in an instant, angrily trying to pull Impulse off his uncle.

The young time traveler looked up at him with a glaring pout. "No way! He's my grandpa! I don't get any time with him! You're the lucky one who knows him!"

"What do you mean by that?" Wally jolted back a moment. He was the lucky one? That Wally-Flash and Blue Bird looked like they might be his uncle's age at the most; at the least they were in their early twenties.

"Bart," 'Robin' ordered, somewhat exasperated, "get off. You're crushing your grandpa."

"What's all this talk about Grandpa!" Flash started. "I'm not even a DAD yet!"

Impulse's face fell a little, realizing the truth. "Oh, right."

"They say they're time travelers," Wally growled as the kid let go of Flash so he could stand. He did, glancing once at his nephew before really taking a good look at the kid in front of him. Seeing Flash and Impulse together, anyone could tell they were related. They had the exact same expressions and ticks. Wally couldn't help but feel a little jealously. "Some older me and older Rob appeared with them, then took off after some other guy who slipped past us."

"Warp," 'Robin' interjected, glancing up from his computer for a moment. "He's a time traveling thief. I was out with Ni—Blue Bird when we heard an alarm go off. Flash was fighting the guy when we got there. Why were you—"

"Wally ran through Manchester and I followed," Impulse added, looking up at Flash expectantly. It was clear he wanted to do something other than talk to them about what happened. "Slow night. A lot of those in dullsville."

Flash couldn't help but to smile fondly a bit, chancing a glance at Wally. Wally folded his arms grumpily. He wasn't like this kid. Not at all.

"Ah." The teen wonder stopped typing for a moment, twisting his lips at the code in front of him. "Harder than I thought. Imp, mind checking this thing out for a sec?"

"But I wanna…" he whined, jerking his head around from his friend to his grandpa.

"Give me two minutes and I won't ask again until the others get back." 'Robin' gave him a compassionate smile. He clearly was reading the boy's mind, or wanted to do something similar.

Impulse glanced once at 'Robin', then to Flash. He hesitated, first time they saw that happen all night, then dashed over to the teen wonder's side. Quickly he looked over the piece of machinery, assessing it quickly. "Kinda looks like a viewfinder and holoprojector from back home. They make great games."

"How about something along the lines of concentrated energy?"

"Like a sonic blaster?" he looked over it again and nodded. "Guess it's a little like one of those."

"How does it work?" 'Robin' fingered through the code again, a forever present thinking gaze on his face.

"Well you tap the right panels on the sides," Impulse pointed out, "then tap the center."

"Any order to the panels?"

"There's a few options." Everyone watched dumbfounded as the two went back and forth about this little piece of machinery, one asking questions and looking through his findings in the programming while the other answered and put little tidbits about video games in it. A few of the teens were tense, while others had definite opinions of their own.

Robin was having a hard time keeping up, something that hadn't happened in quite some time. This 'Robin' was brilliantly smart and much better with computers than he was. Plus he wasn't freaking out at the whole time travel thing. If it were him, he probably would have panicked for a few minutes, especially if Batman wasn't with him.

And seeing 'Blue Bird' was him in the future, and Batman was still around and wanted to be with him, and had a 'Robin' in the field, well that left a lot of openings for his future. For once since the whole disastrous training mission, he felt relief. He didn't have to become Batman. Batman wouldn't be upset by it either. He needed him as Robin right then, but when he grew up, another Robin was ready to help the man out. A crazy thought hit him.

'I get a brother!'

Wally was still scowling at Impulse, not at all happy with the possibilities running through his head. He was Flash? And this kid was Uncle Barry's grandkid? Who had no time with him at all? From the 30th century? That was just plain wrong on so many levels. Sure one day he wanted to be Flash, but really, why would there be two of them? Everything Impulse, Bart, said drove him around in circles. '30th century my butt.'

Flash though watched the two kids with a bemused smirk on his face. Before him was a kid who reminded him of Wally when he first gained his powers, and even a little more now. He also reminded him of himself growing up, especially with how bright he seemed, though he did go back to video games just a little too much for Barry's comfort. And though the kid called him Grandpa, he saw definite traits from Iris in him. The kid's voice reminded him of his dad.

"There! Two minutes!" Impulse stated flatly. "Now can I—"

"Sure fine." 'Robin' unplugged his computer from the gizmo. "Can't get much out of this thing now anyway. Just stay in hearing range okay? We'll have to leave once they get back."

A/N: this looked like a good spot to stop for a bit, so I did. Got a quick explanation of how Tim and Bart joined the DC universe, without going too far into the details. I think Bart actually is three when he meets Tim. Not actually sure. He's two when he meets Wally, got the comics to prove it. One reason I love Bart is because of how childish he is, but is still a good teen over all. Funny as anything. Tim kinda thinks of him as a younger brother, so they work really well together dynamics wise. As for why Tim's being so understanding, he lost his mom not too long ago and his dad's not in the best of health at this point. If he could see his mom again, he probably would. Bart never got to know any of his immediate family for quite some time. Hence Bart's lovable reaction to everything.

And I think his favorite phrase is "I'm bored". Gotta love Bart.
