Yes, with some interesting potential.

You were unsure about this next test, so you decided to probe to see some possible outcomes. You asked the "You in Alex" to try and emulate possible reactions she might have.

"Well there is the first option of her not remembering. She would probably be confused and panicked, so in that case we need proof she came her of her own will. Probably should record something." Alex said, going over the first option for what can happen when your 'clone' disappears/is returned to you. You nod and write down to *Record a video* as backup.

"Next, if she remembers but felt like she wasn't in control. She might be kinda mad, but would probably not blame you totally. As 'You slash I' didn't know, and you've been very clear to not **** your powers. Though I'm not sure what else she might do, as 'I' won't be in here anymore." Alex continued, making a little joke at the end to try and lighten the mood.

"Another thought, her mind might try and justify things. You know like those Possession stories, where people discussed how people would react to being controlled. If the 'you' in here is buried deep, and she would believe all these actions were hers. In this case, she might not even believe your powers are real." She said, letting you mull it over.

"Any other possibility?" You ask, not really liking the options your 'twin' told you. You had an idea of a 4th possibility...

"You're thinking about the same thing as me, that there is a chance she is left open to suggestion, and you can influence her. You're scared of changing her, of erasing or destroying who she is. That final option, and the one your worried about." Alex hit the nail on the head, it was a troubling result to consider.

You weren't some psychopath, who could just ignore how Alex might feel, or the moral implications of partial or total 'identity ****'. You weren't a philosopher, but you knew about the idea of the Ship of Theseus, if you replace parts of a ship, is it still the same ship. There was also the "What's original?" question you'd seen on a forum, questioning when the alterations to something change it into being 'original'. At what point does something lose it's identity and gain a new one? Plus the question of consent if you change her to do what you want.

All that and more bounced around your head, you started pulling into your mind, before getting ripped out by Alex grabbing your face. She spoke with a soft and comforting tone.

"THIS is why she would like you, even considering this option, you are worried about hurting her. You worry about what is objectively right and wrong, even when a power shows up in your lap, one which turns all understanding of the world on it's head." She caressed your face, in a soothing manner. "You could literally turn her into whatever you want, indulge in your biggest fantasies, but you worry about if you should, instead of doing it just because you could."

"How about I tell you 'my' fantasies, what fetishes and things she dreamed of trying. Luckily you are able to get a peak into her mind, so you can build potential changes for her. I'll write the script for the video in case of the memory loss option, while you can write down her turn ons and offs, and build a script for altering her." Alex said, pointing out the advantage of having 'me' in 'her'.

From there, you began building a theoretical 'brain-tweaking' script. You accepted that so long as you didn't touch the 'core' of her, that being [A girl who likes to stay fit and take care of those close to her], then you wouldn't be erasing her identity, but more like adjusting her 'mental clothing' in a sense. You were surprised at the changes she wished she could just 'have' because she struggled with making those changes.

The list of stuff from her mind was kinda long, but that makes sense, you were basically trying to summarize a person's whole personality levels. You started marking down the 'importance' of each thing, stuff like [kind] and [studious] were marked with 1 star (*), meaning they were rather important. While stuff like [dislikes any men flirting with her at the gym] and [obsessed with mobile games] as 3 star, stuff not really important enough to avoid, but you could potentially change. Finally 4 star or above was stuff Alex didn't seem to hold in importance, some of the stuff was even underlined, marking stuff she wants to change, like her hesitancy to date right now after her ex having cheated on her.

(For the sake of things, the order of importance is: 1 star=Core personality related to 'who' she is. 2 star=Important beliefs or instincts. 3 star=Minor stuff she wouldn't change, but wouldn't hold to either. 4 star or more=Stuff she wouldn't miss, bordering on stuff she'd rather loose.)

While you were preparing your 'monologue' about how she would change. Alex(You) was making a video to try and justify a possible memory lapse, about how you discovered memory wiping powers, so you wanted to try a 'longer duration', but you weren't sure if it would wipe out the memories of agreeing to testing the power.

This took a bit, so you both had the sandwiches Alex had bought earlier. Alex asked if she could see your current draft, you passed her your phone, she read for a bit before asking if she could edit a few points. You let her edit it and then show you the changes, once you saw them you were caught off guard.

"Are you Sure we should go through with these? Would it really be alright to add such changes?" You were still extremely hesitant to try these changes. You might consider these changes, but you didn't want to do anything more than necessary.

"Yes, I'm adding what's necessary. You know this level might be needed to ensure nothing bad happens to you. We don't know if you are the only person with powers, if others might figure out stuff is going on, she needs these, if they can be applied." She said "None of these cause repulsion, the Alex part fully agrees these are needed, if begrudgingly. It's not that she wouldn't do these, just that they aren't her first choice of decisions."

Mulling over the choices, you decided to trust your other self, you wouldn't lie to yourself, and you could feel him. No bluffs, he genuinely believed this was necessary.

You prepared to run the experiment, holding her hands and sitting at the table, you wanted to keep control over the situation. Your phone was propped up so you could just scroll and read it. And so, you started to 'pull' your mental copy back in, and then the memories flooded in.

You remembered everything your 'copy' did, from when your copy first dropped into Alex, to when you pulled him back to join you. It was like you recorded 2 perspectives, then spliced them together, then added them back in. The feeling of being in control of her body, the confidence he felt as Alex, the slight arousal at teasing himself(that was a bit confusing for you THB).You could remember her driving to your place, then walking and making an order for you both, flirting with the female cashier(seemingly the you that did that). Testing your powers all the way up to recording the video and going through with the test, 'your' vision of your face fading.

You finally zoned back in, feeling like you'd just went through a multi-hour dream, but you looked at your phone and it was not even a minute. Alex seemed to just sit there, with a zoned out look, just staring blankly away. You lifted up your one hand, letting go of hers at the same time, and waved in front of her eyes. She didn't seem to follow at all.

You were quite nervous, it seemed like she might be 'hypnotized' but you had to check.

"Alex, Can you hear me?"

"Yes..." she replied, her voice more like a murmur, barely making it out.

"Are you hypnotized?"

"I think so..." Is this real, could it be real?!

You breathed in, steeling yourself for what you were about to do.

"Alex. You will become..." You said, looking at your phone for the changes you were about to apply to her.
