Let's have a completely normal scientific interview, with no ulterior motives

A few minutes later, Roy found himself upstairs, sitting on an off-white sofa in the living room, wearing a microphone headset that Samantha had supplied. She was sitting upright, with perfect posture, on the other side of the sofa, wearing an identical and matching headset, her lab coat removed due to the warmer temperature of the ground floor. In front of them on the coffee table was a laptop, both of their USB microphones plugged into it, the screen displaying some recording program Roy was unfamiliar with. Roy was staring at the screen intently, trying desperately to disregard the uncomfortably close Samantha. Roy had been around attractive women before, but considering the woman next to him used be (or rather, still was) his best guy friend, and she had a body that could only be the product of unbelievable feats of super science...

Well, let's just say it was a little awkward for him.

He could see now, with her lab coat removed, that her top wasn't just a T-shirt stretched near to its breaking point by her impressive assets, but rather a sexy crop top, seemingly designed to give her just a bit of a "rocker girl" aesthetic. With her eyebrow piercing, lavender hair, and (now that he noticed them) black skate shoes, he had to appreciate that this Sam knew how to pull off a casual look. It stood in stark contrast to the Sam he was familiar with. And even putting their dress sense aside, even the physical features they shared seemed different on Samantha. Dude Sam's freckles made him look like Ron Weasley's stunt double; Samantha's freckles made her look like the next big Hollywood starlet. Dude Sam's glasses brought to mind Revenge of the Nerds; Samantha's glasses brought to mind "Sexy Librarian". It was like night and day!

Samantha reached forward to hit a key on the laptop to start the recording (forcing Roy to work his damnedest to not stare at her ample rear), and settled back into her previous position. As she adjusted her glasses, she began speaking; "Beginning Interview One with Subject Alpha, that being myself, and Control Alpha, my lab assistant Roy." Turning to him, she continued, "It's important we establish a baseline for what the Retroactive Timeline Manipulation Device, or RTMD, is capable of. To that end, please tell me who I was before the experiment began, as best as you can remember."

"Well, uh, for one," Roy began, "you were a dude."

She nodded, and motioned for Roy to continue.

"Um... you were shorter too. We used to be about the same height, five foot nine the last time I checked. And I don't think you used to work out much. Or dye your hair."

Samantha held up a hand to stop Roy. "Please stick to observable physical differences, not speculation about habits or lifestyle." She seemed a little upset at Roy's assumption. "While I can assure you I take care of my physical well being as best as I am able, exercise included, I don't think I've ever dyed my hair."

Roy laughed at her assertion. Dude Sam could be oblivious, but this was something else. "Oh yeah, because purple is a natural hair color," he snarked at her despite himself.

She tightened her lips in annoyance at that, crossing her arms under her bust. "Purple is a natural hair color, Roy. There's no need to be rude about this. My mother has purple hair, my grandmother has purple hair... Just because it's rare doesn't mean it's automatically artificial."

Roy was about to shoot back at her again, but his common sense prevailed. It was a silly thing to get defensive about, but nonetheless, he decided it was better to just keep quiet about it. "Anyway, you used to be a redhead. Had the whole ginger kid look going. And, uh, I'm not sure if this counts as 'observable physical differences', but you didn't have an eyebrow ring. And I don't think I've ever seen you wear a "Cattle Mutilation" shirt."

Samantha nodded along with this, a small frown accompanying the motion. "In that case, I have to pity myself, apparently having never had the chance to enjoy the musical stylings of Cattle Mutilation."

Roy balked. "Wait, Cattle Mutilation is a band? I thought it was... like, a conspiracy theory shirt. What kind of music do they even play?"

Her eyes suddenly lit up with excitement. "Oh, it's incredible! I'm not sure they can be classified in any meaningful way, but if I had to do so, I'd say they play Electronic Glam Punk."

Roy was lost, as he often was when Sam was excited about something he was talking about, but this was a new one. "Yeah, I can honestly say you've never played any of their music for me before. I doubt I'd forget something like that."

She leaned forward and took the laptop off the table and pulled it onto her lap. A moment later she pulled up a Youtube video for one of their songs. Roy had to admit, they weren't half bad, assuming you liked the kind of music that was designed to be listened to while both angry at the establishment and high on ecstasy.

As the song finished, Roy nodded in agreement. "I think I could enjoy something like that," Roy admitted. "Thanks Sam... antha."

"Well, in any case," she replied, "this provides evidence for another of the device's features; the machine can not only change someone's physical form, but also their experiences." She again crossed her arms under her bust. Having seen it twice now, Roy had to wonder if it was a nervous tic. "After all, I could tell you all of the lyrics to most of their songs, so it stands to reason that such information must have been given to me somehow." She cocked her head to the side, and regarded Roy strangely. There was the unmistakably Sam like glint of curiosity in her eyes. "I've got kind of a weird question for you, Roy."

Roy nodded. In spite of himself, and his occasional glances at her body, he was beginning to see more and more of the Sam he knew in this girl, despite her new preferences. Most of that nervous awkwardness was already beginning to fade away. "Fire away," he replied.

She took a moment first to pause the recording software. Roy found that strange; for someone as meticulous at taking notes as Sam/Samantha was, apparently she didn't want this question on the recording. "Did you and the old Sam ever experience sexual intercourse?" she asked him, with no hint of irony or humor in her tone.

When Roy failed to answer, and simply sat there with his mouth hanging open, she decided to clarify:

"With each other, I mean."
