How do you make a flashback sequence more interesting?

[Marscaleb]

I have a flashback sequence that is going to take up a whole chapter. It needs to happen because it's where I give the reader a lot of information they need. And I figured it would be more interesting to show a lot of this information through the eyes of the main character rather than telling the reader with a wall-of-text info-dump.

But once I wrote the first draft, I found that it was far from exciting. Because it is a flashback sequence, the reader is already aware of the outcome. For example, if I had a part where the MC's life was in danger, (I don't, but still,) the risk would be nullified because we've already seen the MC alive in the rest of the book. And while less-apparent but more critical, I can't make the MC grow because we already have established what kind of person she is after this flashback. In my case, I can't even make this about "showing how she became who she is" because I also have earlier content that shows what she's like before this flashback sequence.

So quite frankly, there are no stakes here. Nothing is at risk, neither outwardly nor inwardly. Which means I can't advance any plot for the duration of this flashback.

So how do I make this flashback sequence interesting? How do I make it engaging?

I have quite a bit of flashbacks in my project.
I always make sure that the flashbacks reveal new things or expand on what we already kn ow.
For example, the flashback sequence that takes up a whole chapter in mine.... we already know this character's parents left her. That her dad wasnt univerally liked. That this character had an unhealthy relationship with her friend, and had a volitile relationship with her lover. We also know she doesnt like the MC because she is from the desert.

BUT

The flashbacks go deeper into these things that we've learned about her. It shows her relationship with her mom and the bruises she helped her come cover up. It shows how she was happy being with her friend and emotionally latched on to him. It shows how she was only with her lover because he was an acceptable choice. Also shows how she negatively rationalized certain things because of the people in her life growing up.

So, im not reiterating what is already known. These flashbacks fill in the gaps of "why".
I think, if you arent answering the "who what when why" then the flashbacks serve no purpose.

If the sole purpose of the flashback is to give the reader information, I would cut it. You don't need info-dumps either.

Not knowing anything about your story or the information being presented, it's impossible for me to say which bits of information are necessary and which are not, but it's almost always true that the reader needs less than we think.

Can you distill the info down into a few bits? Can you get those bits across to the reader in a less obtrusive way? Maybe some of those bits can be revealed later, or maybe you don't need them at all.

If you've been building suspense via a particular gap in knowledge, then the flashback would be a release of that suspense. e.g. we finally learn how Mike lost his arm.

So quite frankly, there are no stakes here. Nothing is at risk, neither outwardly nor inwardly. Which means I can't advance any plot for the duration of this flashback.

A flashback scene can still have stakes. They could be mostly within the past (did the hostage/love interest survive?) or they could reflect on future possibilities (were his actions genuinely unforgivable, meaning his partner's coldness is forever justified?). I have a hard time seeing a flashback as advancing the plot, however, unless it provides new information or a revelation for a character rather than just the reader.

Because it is a flashback sequence, the reader is already aware of the outcome. For example, if I had a part where the MC's life was in danger, (I don't, but still,) the risk would be nullified because we've already seen the MC alive in the rest of the book. And while less-apparent but more critical, I can't make the MC grow because we already have established what kind of person she is after this flashback. In my case, I can't even make this about "showing how she became who she is" because I also have earlier content that shows what she's like before this flashback sequence.

It would often feature the 'why' or 'how.' Sure, we know she's alive, but we might want to know why she fears echidnas.

But once I wrote the first draft, I found that it was far from exciting.

Good to follow your gut. If it feels boring to you, it probably is boring.

So how do I make this flashback sequence interesting?

There's something wrong with this premise. It seems to imply that the needed info is medicine masked with peanut butter. Dude, you could have the best peanut butter, with bewbs, explosions, passionate soliloquies etc., but it won't really help. The medicine is either good or it isn't. Poor medicine will feel like poor pacing no matter how good the scenecraft is. I would do three things combined in this case:
1. Raise one or two questions earlier that the information might address.
2. Change the information so it actually is interesting.
3. Summarize the heck out of whatever boring yet somehow vital parts remain. You might be surprised at how much you can leave out.

After that, your current self has done his/her best. Give it a break and be kind to the author. Leave the thing in whatever state it's in and finish the rest of the book. It may not reveal its satisfying form until the rest of the story is fully realised.
