TAT (Half-inspired by that earlier Anon's "home doesn't feel home anymore" thing): Scifi where FTL doesn't exist, any spaceships travel at just below light speed, so time dilation, so they can be a few months or years, but then decades or centuries pass back on Earth. "Now it's two months out and it's two months back/ Pushing the speed of light/Twenty years on your homeworld's track/Pushing the speed of light/And your friends are gone and your lover, too..." ...Sorry. But, do you get my idea?

I get it. Oh boy do I get it. This is why I think I love Cap so much. There’s something so heartbreaking about a man out of time.

The other Nonny inspired me, so what if in a scifi way the bad guys capture A and wire him up to some machine which makes him relieve his worst memories&nightmares, with some science shit the rest of his team is sitting there watching the whole thing. A was always quite and jumpy, and the team was often annoyed by it. And now this way they found out why he is the way he is and they cry, but can't save him for a long time. And when they somehow get to him, he's panicing and they comfort him.

You know, there was a season 9 or 10 Stargate: SG1 episode that was kind of similar to this.

The team was on this planet and Cam hooked up with one of their scientists. In the morning she was found dead and the people of the planet had a memory machine that would let them see into other people’s memories, and even alter them. Cam was accused of the murder and they used it on him to try and find out if he did it or not. Sam was with him for most of it and saw a lot of painful things from his past. It took a terrible toll on Cam who got really emotional during the process.

It’s a really fantastic trope that we need to see more often.
