Brad finds Magenta out on the porch, sitting in a deckchair, stargazing, perhaps looking for her home. He sits next to her and lights a cigarette. This gets her attention instantly.
"Can I have one?"
Brad shakes his head, "I don't know how to tell you this, but you don't smoke." He takes a drag on it, getting an envious look from his fellow insomniac. She glares at him in disgust, then unexpectedly places her hand over his, her eyes closed tightly in aversion. Brad looks at her curiously, then at their clasped hands; he can hear her rather labored breathing, as though she herself can't believe what she's doing.
"Are you all right? What is this?"
Magenta opens her eyes, giving him the same soft, almost lovesick look that had unsettled him earlier. "She likes you." She states simply. "She," Magenta makes an up-and-down gesture at herself, "is…quite fond of you. And I get the side-effects," she huffs. "This is not under my control, Majors, understand? I have no choice but to…feel this way." She removes her hand, raising it to her forehead wearily. "You're such an ass."
"So I've heard."
She turns to him with a smile, eyes sparkling with silent laughter. Her breath catches in her throat, and after taking a moment to compose herself she continues, "You can't be so upset that your girlfriend isn't who you thought she was. You have no idea how important you are to her."
Brad reaches out and touches her face, transfixed. This time she doesn't pull away, allows his curious caress. She leans into it with a soft crooning moan, helpless for the moment. "Don't. Stop," she whispers, "Don't stop."
With considerable effort, Brad drags himself away, not even trusting himself to look at her, cutting short their moment of weakness of the flesh before it can lead to anything regrettable.
"I'm sorry; I don't know what got into me."
Magenta drops her face in her hands, suddenly robbed of his touch, nodding agreement. "Perfectly all right, at least one of us has some self-control. I just…want…"
"Don't finish that sentence."
Taking a sudden deep, fortifying breath, Magenta straightens back up and faces him, flicking him a disdainful look that tells him she's okay. Brad can't help but feel that they're somehow friends now.
"Tell me, what else is going to happen to Janet? What other changes should I expect?"
Magenta shrugs, then considers, "Well, there's the increased sex drive—humans mustn't have much of one to speak of—and she'll have vastly improved night vision, she'll lose this ridiculous pink in a matter of days, hopefully." She inspects her hands derisively. "Her blood should be changing back to its normal color soon. Red blood, whoever heard of such a thing! Until she adapts to this environment again it'll be like she's never seen the sun before."
"Yeah, I noticed, even as you her eyes are sensitive to the light."
Magenta nods, "She'll probably have to wear sunglasses, even in the house, until she's used to it again. There's no telling how long that should take. You'll need to come up with a cover story, people close to her will notice unless they're blind."
"Janet mentioned something else, something she'd hoped to get anyway. She wants it to be a surprise. Do you know what that is?"
She smirks, a knowing and amused look on her face, "I do. But if she wants it to be a surprise, far be it from me to spoil it for you. I do hope she gets it. You won't like it, I know that already. It isn't bad, just…different. It might scare you, if the rest of it has, but you might not mind it after a while. Riff-Raff thinks it's adorable."
Brad looks puzzled, "Does…everyone from your planet…have it?"
"The women do."
He nods, chalking it up as a girl thing, "So, do you?"
She looks affronted, as though he'd asked her something very personal. "Well…yes."
"Great! Could you show me? Just so I know what to expect?"
Magenta's eyes go wider still, feeling her face grow warm, "For…you? N-no, that's…that's out of the question, Majors. I couldn't! Even if I could…they'd kill me! Don't let Riff hear you ask that, either, if you value your skin. Don't even mention it to him."
Brad is taken aback by the seriousness of this little secret of hers, "Thanks for the tip. It's private, then?"
"Yes, very. You don't realize…you don't even know what you just said to me." She fails to suppress a shriek of nervous giggles. She tries to hide her smile behind a scowl, though her eyes hold an expression that's almost flattered. She gets up to go back inside, "Sleep well, Brad," she softly says over her shoulder.
"Goodnight, 'Genta," Brad replies, following her into the house. He goes back to his bed and finds it empty. After puzzling over this, he lies down to wait for Janet's return.
Magenta finds her in bed with Riff-Raff, just laying with him and speaking in low voices. Rebuking herself inwardly for her flash of anger—they must be sharing a weakness for each other's mate—she creeps out again before she is seen.
"We really shouldn't," Janet murmurs, a cozy attempt at a protest.
"We aren't doing anything wrong. Everything is fine," Riff assures her. "You're well within your rights to come to me, and it's still my job to look after you. Think of this as making up for lost time." He sounds genuinely regretful at having lost that time with her. Unable to argue with his reasoning, Janet allows herself to relax with him.
"I hope there won't be any more problems with Brad. I can't help what's happened, I'm just as scared as he is!"
"I know. I hope so, too. The machine's almost fixed, don't worry. The rest, you two will have to cope with on your own. Worst case scenario, you'll still have us."
She gives him a cuddle, "This feels so good. Can you imagine Magenta pawing at Brad like this?" She giggles at the thought.
"Who's to say she isn't?" Riff counters. This is too much for them, and they cackle uproariously in perfect unison. They stop together, breathless, smiles flickering like moth's wings at the corners of their lips. Janet tears herself away before she becomes too entranced and unable to stop herself.
"I'd better go. But thank you, I'm so glad you're here." She gets out of bed and returns to Brad's room, climbing back into bed with him. He studies her in the moonlight which now streams through the window. Despite her assurances that she'd never resembled her sister, Brad suspects he'd find out for himself shortly. As she gets settled back in, he finds himself wondering how these changes her alter-ego is undergoing will affect their day-to-day lives. How would they explain her sudden change in appearance? He'd leave that to Janet to come up with an excuse. They might as well start off by keeping their stories straight. He wonders what 'surprise' awaits them, which Janet wants so much and Magenta is so sure he'll hate. Guiltily, he hopes it won't be too conspicuous. Both women seem to hold it as something special. Brad holds Janet from behind, flattening her hair down, hoping that when the time comes for her big reveal that he can be understanding about it.
