Any constructive criticism welcome

Before I start, let me give you a little background: my brother is an art major/engineering minor, hoping to go into special effects production. After he graduated, he showed me this commission he's working on, a trick mirror for a haunted house. Actually, that's a lie, he's a dick so I found his project when he tried to use it on me.

I woke up one Saturday, went to brush my teeth and saw my reflection wasn't reversed like it's supposed to be.; Instead of raising its left hand when I raised my right, it also raised its right, as if I was watching a real time video of myself.

"Hey asshat, what did you do to the mirror?" I called out to him.

"Oh, shit, I fucked up," I heard from a hidden speaker.

"Just fix it," I said as he walked into the room, but he ignored me and talked at me about the details about the technical aspects. I didn't really pay attention, but basically it's a computer screen and webcam that he controls on his tablet. If you're interested, look up "raspberry pi mirror" and you'll get an idea of what he did.

"No no no, watch," he said, and started found stuff on the tablet. The screen went back to mirror image, and Mike pulled me into the next room. We watched the tablet for a few minutes, watching the bathroom camera in true creeper fashion. My mom was the next one in, and we watched as she started brushing her hair.

"Ready?" He asked with a devious smile, and messed with the tablet a little. He pushed a button and my mom dropped her brush and screamed.

"MICHAEL JAMES ROBINSON, get in here right now!" He started laughing hysterically, and after sweet talking his way back onto mom's good side, he showed he a replay. On the left was our view, mom screaming and dropping her brush, and in the right was her view, brushing her hair and then a jump scare of a Mike popping in and screaming at her.

I know it's a dick move, but I didn't have anything better to do, so I spent the next few weeks finding guinea pigs for him. I had my aunt give me a "makeup lesson" and Mike put it on a two second lag. My aunt spent so much time looking back at the mirror trying to catch it I ended up looking like a Picasso. For my cousin, we recorded me walking in and asking to borrow her iPod, and played it back without me entering the room. My mom then started tipping guests off when they visited, so it wasn't until they went on vacation that we were able to bring my neighbor in.

Mike invited Krista over to watch Netflix and eat wings, with me on mirror creep duty. He would direct her to the bathroom to get the sauce off, and I was going to set the justmpscare, keep it easy, with me on the tablet doing controls and Mike watching on his phone live. He told me to count to five after she starts washing her hands, but when Krista came in she looked straight into the camera.

"Hey," she said sweetly, "long time no see. How's it going?" I froze, not sure how to respond. I decided to try to play dumb,

"Uh, hello? What is this, Krista, can you-"

"Going to play that way, huh? Oh well, see you around." She interrupted, and went out again. I freaked out so I shut off the internet router and ran to the living room.

"Hey, Mike, is the internet out for you?" Mike looked a little confused, and Krista seemed non chalant, smiled and said hello to me.

"Uh, yeah? I mean, yeah, Netflix cut out, uhh, shit, this might be a while, Madison, why don't you take Krista to Kroger and get some snacks while I fix this?" I gave him a death stare but Krista agreed, so we drove out for some chips. I kept trying to pick her brain, get a feel for what was happening, but she didn't let on anything was amiss. I dropped her out front and went to "find a parking spot."

"Mike, what the fuck? Could she hear me?"

"No, if I couldn't she couldn't, did she say anything in the car?"

"No, what's going on?"

"I don't know, give me twenty minutes and then get her back in the bathroom when you get home."

"What? How?!"

"I don't know, fuck, you figure something out! I have something else to do." He hung up, and twenty minutes later we were back home.

"Hi ladies, what did you pick?" Mike awkwardly asked.

"Lays," I said she threw the bag at him. "uh, Krista, can I ask you something? It's a girl thing."

"Oh, ok-" I dragged her into the bathroom, looking at the floor and my shoes but not at her our the mirror, and blabbered for a minute about the cute cashier;and then pulled her back out before she could reply. Mike was pale.

"Yeah, uh, internet's down, called the company, they're going to send someone out..." he trailed off, and I apologized and sent Krista home.

"Well?" I asked, but he walked by me and went into his room, to his computer. He messed around for a little and then played me back the earlier video; Krista' s view on the left, the screen acting as a camera, and our view on the right, her talking to herself.

"Ready?" He asked. He played the second video; on the left was my view while I was with Krista, the screen recording and playing it back to act like a real mirror. In the right was Mike's view, Krista and I talking, but it was focused on either mirror in the back. There was a slight infinity effect that was somewhat disorienting, but I could see us again, with my reflection blabbering about the cute cashier, and Krista's screaming and crying, banging on the glass.

"Did you do this?" I asked shakily,"don't you dare fucking lie to me, Mike, is this some bullshit editing of yours?"

Mike just looked at me and shook his head. I went into my mom's office and pulled a paperweight of her desk, and went back to the bathroom. Mine was waiting at the door, but I ignored him and walked in. I turned and covered my eyes so I didn't have to face it, and first smashed the screen to Mike's commission. Still not looking, I did the same to the regular mirror. Mike called his client and said his refund would be in the mail, then we drove to some friend's house to spend the night. Neither of us have looked in a mirror, or even talked to each other since, but Krista' s been texting Mike to reschedule. I don't think we will.
