A blast from the past--who wants a prequel?

Kidd tromped up the stairs to the second floor. He fished his keys out of his pocket and flicked through the bunch, trying to find out the room key. He almost didn't notice the huddled figure pressed against the balcony railing.
It was the off key strain of Marvin Gaye’s ‘Sexual Healing’ that caused a chill to fission down Kidd’s spine. He froze in mid-step.His eyes zeroed in on a strangely dressed figure. It was a girl; she looked like she’d wandered away from a Steampunk gathering with her odd getup. A black top hat was pulled low over her face, hiding her features. Ultimately it was the voice Kidd identified, though it hitched and skipped like a broken record.“Rae?” Kidd called her name in disbelief.Her head flopped back and indeed it was her. He saw that she had trouble focusing on his face and recognized the telltale pupils.“You’re high.” He said shortly.“You’re here.” Rae chirped happily. “Hiiiii!”Kidd shook his head impatiently. What the hell?
“Did you bring the pretty stars for Karla?” Rae asked him, “She likes presents! She liked my fireworks!!” Then the happy expression on her face dimmed, “She’s mad at me.”Kidd knelt down and grabbed Rae’s shoulders. “Karla? Is she here?”The smile came back but this time it was coy. “Uh uh. Can’t tell you. You’re a kitty cat.” She growled at him playfully. “A bad kitty cat.”That almost sat him on his ass. She knew he was a Panther? That explained a lot. Shit!“I’m not going to do anything bad to Karla, Rae. You have to trust me.” He said urgently. “Is she like you? Is she high? Where is she?”“Are we playing twenty questions?” Rae asked him soberly. “Cause that sounded like twenty—”Kidd wanted to growl in frustration but he didn't dare scare her. She’d lock up tighter than a bank vault. He took a slow breath through his teeth, “Rae. Where’s Karla? I have to give her my present.”
“The stars?” Rae guessed excitedly. “Oooh! I can’t wait to see her face!!”He nodded quickly, “That’s right. Let’s go show her the stars--!”He was about to help her to her feet when Rae pulled back with a frown.“No, we have to wait our turn.”Kidd wanted to shake her. He was getting worried. “Wait for what Rae?”“Sexual Healing,” She said like ‘duh’.He was going to throw up. It took him a few deep breaths to gather enough control to ask, “Is it Karla’s turn now?”Rae nodded, blinking guilelessly.Kidd couldn't wait any longer. He started searching Rae for a key. “Rae, so fucking help me, you have to tell me where Karla is--!” He snarled.
She was too far gone. As he searched Rae frantically, she giggled as though he were tickling her. All Kidd could think of was that somewhere in the building behind him was Karla. She was being hurt by someone and he couldn't fucking help her because her best friend was out of her mind high!
“God dammit Rae!” Kidd exploded impatiently.Hang on Karla!
