Aw, all dolled up and everything! His foot taps the ground with restless jubilation for a moment before he all too casually steps off the roof, like he's got a damn flying carpet waiting for him. Of course he doesn't, and he waits until the absolute last moment to fire his grapple-gun. The snapping teeth bite the ledge and halt gravity's pull, and John makes only a soft 'oof' at the likely painful strain to his arms. Meh, he barely notices anyway.

He's hanging just low enough to reach Riddler's hand, which he grasps tightly with an absolutely euphoric Cheshire panther grin.

"Gotcha!" he pulls Riddler as he hits the trigger, drawing the other man closer to him (as opposed to hanging beneath him) for the quick trip up. The momentum carries them both an easy foot above the ledge, making it simple and effortless to land solidly on their feet.

"Hey! Good to see ya!" here, have a brief but very tight, very enthusiastic hug. He pulls back just as quick as he pounced, adapting a slight air of sheepishness. "You're welcome for the lift, by the way." Cue a few skewed giggles.
