And here we have the final chapter. I am thankful for everyone who's taken the time to read this little experiment of mine.

Nightwing and Batman emerged from the portal. Nightwing was helping support his mentor since the damage from the battle started to settle in. Wonder Woman bounced towards them ready to help, but that wasn't something Batman wanted. Instead, he turned his attention to the portal, ordering Johnny Quick to stop immediately.

What happened next was shocking. As he stopped, the once youthful speedster was on the edge of old age. Flash was the one two approach him before he fell over. Everyone was shocked by the change. Everyone but Batman that is. It was like he knew that this would happen.

Even Johnny Quick seemed to pick up on it. A simple inquiry about him being faster than Flash being false conformed that for him. However, he wasn't upset. In fact, the aged speedster was impressed. That's all he needed before succumbing to the aging effects of the ordeal.

The moment didn't last long, as Ultraman threw in a snide remark for them to leave. Even when reminded about how they all almost died, he didn't seem fazed. He was more concerned with the Crime Syndicate and how the Justice League were acting like wannabe cops, who thought they could take the Crime Syndicate in.

He didn't get far with that comment before Martian Manhunter made his presence known. He wasn't even alone as several officials, the president included, stormed the base shortly after.

Cruising in their newly acquired transport, the Justice League and Lex followed their malicious cargo. They wanted to keep a close eye on the remaining founding members of the Crime Syndicate before they returned home.

Batman was keenly inspecting Nightwing for injuries, keeping a firm grip on his ward's face. When he found very little physical damage, he was relieved. That did not, however, alleviate his other grievances. Like the fact that Nightwing ran off in the first place.

"You're grounded." Batman bluntly remarked. "No Nightwing for the next two weeks."

"Understood." Nightwing agreed, well aware that this would happen.

"You're really going to lecture him now?" Superman argued. "After everything he just went through?"

Everyone's attention fell on them. No one said a word, but that didn't stop them from taking note of the disagreement. Batman's focus remained on Nightwing.

"This doesn't concern you."

"That doesn't seem fair. He gets kidnapped and you're stripping his mantel from him because of it?"

"Superman." Nightwing sighed, hoping that it would stop the argument.

"You seem to forget that he's my child." Batman reminded. "And as such, will be punished for sneaking out. I'm not punishing him for getting captured, that wasn't intended, but instead for sneaking out."

"That's still not fair."

Batman's attention finally shifted as he released Nightwing. A displeased grimace shot at the Kryptonian.

"Who would you rather I get mad at? You for agreeing to take him?"

Superman was flabbergasted by the accusation.

"You and I both know that when it comes to Nightwing and things he wants to do, you are easier on him. What seems to be forgotten is the fact that he's still a minor under my care, and as such is my responsibility."

Batman took a breath, ready to conclude the debate.

"He made a bad choice. Good intentions or not, his actions need to be addressed. Remember, he was at the Watch Tower because it was part of his birthday present. To visit, not to get involved in an unexpected abduction ploy."

The group meet up with the president after the Crime Syndicate was properly contained. Thanks were given for their help and some general small talk. Slade's glance at Nightwing was curious, but not totally unexpected.

"You really do look just like him." Slade noted. "Though not as conflicted and livelier."

Nightwing chuckled, startling the man. It wasn't meant to come off as rude or disrespectful, but pleasantly amused. It was puzzling to Slade, who had no idea why he had the reaction.

"I'm sorry." Nightwing amusingly apologized. "It's just, on my world, we're not exactly on the friendliest of terms. I couldn't imagine this outcome. It's a little different. A nice kind of different."

The statement amused Slade, entertained by the explanation. He wasn't even offended by the implication.

"I can see how this comes as a bit of surprise to you."

"Yeah."

They both laughed, which was an unusual experience for the Justice League. Nightwing wasn't the only one to interact with their world's Slade Wilson, but he was the only one who could make it sound normal.

"I think it's time we get you home." Lex announced.

Everyone was ready to go. The only one missing was Martian Manhunter, who was interacting with Rose. With romantic undertones from what could be deduced. Noting this Wonder Woman went to get him. It took them a few minutes before they both made their way back to the group. Al Nightwing got a glimpse of was Martian Manhunter commenting on how she could be evil.

"How would you describe our Rose Wilson?" Wonder Woman inquired.

"Like dad, but a little more on the misguided side." Nightwing described. "Has potential if given the choice."

He didn't know if that helped Martian Manhunter, but it was something. With the League now fully regrouped, they were all set to head home.

"I want to thank you again for your help." Lex admitted, activating his handheld transporter.

"You're welcome." Superman replied. "It was an honor to help and a pleasure to meet you."

Lex aimed the machine towards them and fully activated it. The Justice League began to blur before they completely vanished.

Now I may try other Thomas Wayne Jr. and Dick Grayson fics down the road, but this did give me the opportunity to test out their interaction out a bit.
