Companions react to glitches! Engine shenanigans like violent ragdolling or flying cars, *that one* engine trick where you can fly on it, out-of-bounds, settlement structures defying all laws of nature, dupes, etc.
Cait: Cait watched in horror as the raider she shot flew upwards instead of falling on his back. Then he collapsed boneless in the road, his limbs at impossible angles. It was as if he hadn't weighed anything at all. Cait frowned and shook her head as if it would knock the image away. "I never saw any of this shit when I was on chems," she scowled.
Codsworth: Codsworth couldn't believe his three metal eyes. There were two settlers shopping at the same stall in Diamond City. Both women wore the same buttoned-down shirt with tattered jeans. Their dark hair was styled in matching ponytails. And they moved with identical motions; hands on their hips, heads scanning left-to-right across the wares, then folding their arms and simultaneously asking for a discount. "Um, sir/mum?" Codsworth nudged Sole to look at the identical settlers. "I can't imagine they're twins. Do you think...?" He didn't want to accuse anyone of being a synth, but their similarities were too close for comfort.
Curie: Curie had been staring at the brahmin with its heads stuck in a rock all afternoon. She had measured the animal. Drew its blood. Took its temperature. Finally, Curie relented and pulled Sole from an important meeting with the Minutemen. "I do apologize, Sole, but this could not wait. Look..." They both watched as the brahmin continued to walk forward, moving nowhere, half its body seemingly trapped not between anything, but inside the rock itself. "Do we call someone? I genuinely do not know what to do."
Danse: "Institute bastards!" Danse's profanity instantly roused the soldiers stationed at camp to their feet, but Sole made it to the front of the fold first. They watched as Danse fired at a charging gen 2 synth, and it was obvious why the paladin worried. Instead of a usual blank face, there was a chair protruding where the synth's head should be. Danse dispatched the synth quickly, then called Sole over to examine its body. "Look at this abomination," he spat. "What will those cretins think of next in the name of science?"
Deacon: Deacon was already afraid of heights. It was a miracle Sole convinced him to climb to the roof of the abandoned building already. But when he watched two raiders walk into each other and... stay inside themselves... each facing a different direction but walking toward the building, he wiped the sweat from his brow and spoke to Sole in a voice five octaves higher than usual. "Uh, hey partner? We gotta go. Now, if possible."
Hancock: The mayor wasn't sure if that car was floating because of the jet he hit an hour earlier or new Institute technology, but he didn't think it was his place to find out. Hancock simply turned away and walked silently back to Goodneighbor. Let some poor Brotherhood bastard find it first.
MacCready: MacCready shrieked and nearly climbed up Sole at the sight of the car pinwheeling towards them. It was as if the vehicle was weightless, and it clipped through the road itself. Sole pulled on the merc's arm and blindly rushed them both to the safety of an overpass, which the car moved through without noticing them. "What the... I just... I've never seen..." MacCready was speechless, all the breath having left his lungs from his scream moments ago.
Preston: "I know what I'm looking at, Sole. It's the why I still haven't figured out." Preston crossed his arms and stared at the water purifier with a jukebox sticking halfway through it. The pump was still active. And the stereo was playing the Ink Spots. He just couldn't understand how both were possible. "Is it a prank?" Preston asked, mainly to himself. "A very high-tech, creepy prank?"
Piper: "Blue! Blue, get in here!" Sole nearly knocked down the door reaching Piper, but quickly realized she wasn't in danger. In fact, the reporter was positively beaming as she gestured to a table full of purified water. "Look what happens!" Piper placed a water bottle in her satchel, and when she pulled it out, another one came with it. "They're somehow duplicating. Do I have a magic bag, or was the first water bottle special?" She hesitated. "Actually, if you answer that too fast I'll think you're a synth."
Nick: Nick felt like he was going insane. He had swallowed his pride to show Sole, but even they thought it was some elaborate hoax. "I'm telling you, kid. Every time I walk through the door my outfit changes. And when do you ever see me part with my signature coat?" Nick left the room and returned in a plain drifter outfit. He exited again and came back wearing a red sequined dress more befitting of Magnolia than a synth detective. "This is Deacon. I can't explain it. I don't even want to try. But point me to the church, because I'm about to give that spy the what-for."
X6-88: X6 had been in the Institute infirmary all day. Sole stood anxiously by his side, reading his charts and advocating for him to doctors. It was no use. He had holstered his gun, but somehow his arm stayed suspended in the air; hand formed as if still squeezing the trigger. "They may need to replace my defective arm," he stated flatly, trying not to react to the raw emotion in Sole's eyes. "You can't expect me to defend you looking like a gunless cowboy, now can you? People might start approaching me thinking I'm a Minuteman." Sole laughed at that.
