A/N: Okay you'll only understand this if you read Young Justices cannon comic series issue 11. I changed a few things, but it's mostly the same.
Batman and Ra's stood on the runway facing each other with unemotional faces.
"All of this is possible, Detective. If only you'd join me."
Ra's face contorted with anger.
"There's just no pleasing you." Ra's pulls a remote from his green robe and lifts it pointing towards the rocket.
"This remote will launch the rocket now. You see Detective; I've failed in the past by underestimating you. Not this time."
Batman allows a small smirk to cross his face.
"This time…I'm not the one you underestimated."
Batman looks up and Ra's follows his gaze to see Robin standing on the nose of the rocket holding the diamond nose cone.
"Why do the bad guys always say no? They see me standing here with the thing, and still they say no. You're in denial Ra's. Ever thought of "re-nial" instead?"
Robin yells to him as he grapples towards his mentor. Ra's yells in rage and throws a shuriken at Robin's grappling cable. The shuriken cuts the cable and leaves Robin falling.
Robin looked through his belt for an extra grappling hook, but finds nothing. The ground is getting closer and closer, and he's falling faster and faster. He lets out a yelp of surprise when he is caught by his father.
"It's alright I got you."
Robin merely nods as he and Batman land back on the rocket platform. Batman sets his son down.
"Are you okay?"
Robin nods but Batman knows otherwise. He whirls around as he hears footsteps approaching. Ra's steps out of the gloom with the diamond in hand.
"It seems as though I did underestimate the child, but I will still win. I'll destroy all humanity, starting with Gotham."
Batman steps in front of Robin, blocking him from any attacks. He and Robin however do not see Talia step behind them. Robin yelps as he is shot with an electric beam and sinks to his knees. Batman turns around surprised to find Talia the one responsible.
"I am sorry beloved, but this was your choice."
She aimed the gun at Robin just as Batman enveloped the boy in his cape. She glared at Batman as he shot his grappling hook and swung him and Robin to the other adjoining platform.
"Batman to Batcave. Alfred are you seeing this?"
"Yes Master Bruce I am is Master Richard-"
"He's unconscious, but stable. I have to get that diamond, but-"
Batman is cut off by the rocket rumbling. He holds Robin closer and aims his grappling hook. He growls when he realizes he's run out of cable.
A/N: Oh no what will happen? LOL
