And now, tonight on "What happened in between chapters?"...
After attaching the Scale Keystone on the Gateway, the three stand by and wait until the next rift opens. Wyldstyle does some shadowboxing, Gandalf practices his magic by levitating some bricks in air, and Batman is inside his Batmobile, checking everything. After he was finished, he steps out of the vehicle.
"Everything okey-dokey, Bats?" asked Wyldstyle.
"For now," said Batman.
"I meant the car," said Wyldstyle.
"I know," said Batman. "Like I said, it's fine for now."
"Anything you need?" asked Wyldstyle.
"A new engine," answered Batman.
"I'll look for some bricks," said Wyldstyle.
"I already looked," said Batman. "None of the leftover parts here make a sufficient engine to keep the Batmobile stable for a long time."
"So, if the Batmobile keeps on running..." started Wyldstyle.
"...eventually, the engine will give out," said Batman.
"I don't understand what you're talking about," said Gandalf.
"You don't have to understand," said Wyldstyle. "Just focus on your magic and stuff."
Wyldstyle walks towards Batman and looks at the car.
"How long do you think?" asked Wyldstyle.
"According to the computer, the engine will break down if I run at 100 miles per hour for thirty minutes straight," said Batman.
"But you run only at, like, 50-60 on our missions," said Wyldstyle.
"We don't know how long this mission is gonna take, or how many times I'm gonna need the Batmobile," said Batman. "It's best to be prepared for everything."
"Well, if we're lucky, maybe we'll end up in a dimension where they sell parts for cars," said Wyldstyle optimistically.
"Hopefully," replied Batman.
Silence filled the air for a few minutes. Batman and Wyldstyle stared at the Batmobile for a long time while Gandalf was still levitating bricks.
"So..." Wyldstyle broke the silence.
"What?" asked Batman.
"Was kissing me the only option you have or was it a second option?" asked Wyldstyle.
"My first plan was using a frequency-jamming disk, but the Cybermen would've fired if they saw me reaching for it, so I had only one other option," said Batman.
"Did you enjoy it?" asked Wyldstyle.
Batman looks at Wyldstyle.
"I think we've made it clear you like me. So, did you enjoy doing it?" asked Wyldstyle again.
"There's nothing to enjoy about in a life and death situation," said Batman.
"So, your answer is basically, 'The kiss was just a professional decision'," guessed Wyldstyle.
"It wasn't the first time I've done that," said Batman.
"Oh, really?" asked Wyldstyle. "C'mon, Batman. I need details. When was the last time you kissed someone? What's her name?"
Batman was reluctant to answer.
"C'mon, Bats. I thought we were finally becoming friends," said Wyldstyle. "Friends share."
After a few more seconds of silence, Batman speaks. "Wonder Woman."
"Whoa, wait? Wonder Woman? Really?" reacted Wyldstyle.
"It wasn't like that," said Batman. "She and Bruce Wayne were hiding from terrorists. They had to kiss to hide among a crowd."
"Did you enjoy it?" asked Wyldstyle.
"Do you want me to be honest?" replied Batman.
"I do," answered Wyldstyle.
"I did," said Batman. "But I refused to confront me feelings. I waited too long. She's found someone else."
"Why didn't you go after her?" asked Wyldstyle.
"I can't have it both it ways. Fighting crime and having a life," said Batman. "I have to retire from crime-fighting to have a life, and I can't do that. My city needs me."
"But you and Wonder Woman are both superheroes," said Wyldstyle. "Is it hard to date another superhero?"
Batman hangs hid head and didn't respond.
"You know what I think? I think you're just afraid to tell her," said Wyldstyle.
"You can't presume to know what I feel," said Batman. "I know you're intrigued with me, but I'm not interested in talking about my love life."
"If you keep up this attitude, you're gonna grow up alone," said Wyldstyle.
"Maybe it's for the best," said Batman.
Wyldstyle stuttered, but didn't say another word, not knowing how to respond.
"You're a good person, Wyldstyle," said Batman suddenly.
Wyldstyle was surprised.
"Your man is a lucky guy to have someone like you," said Batman.
"Uh, thanks," said Wyldstyle.
The Gateway opens another rift, attracting the attention of the trio.
"Time to go," said Gandalf.
If you remember the sequence of the game, then you know that the trio is going to Metropolis in the next chapter.
