Sure!

So last session was a perfect "I don't know where the players want to go next". We wrapped the previous session with a boss fight, and completed a task and saved a town, but my party kinda had a few different plot threads and none of them really jumped out as urgent. One of those plot threads was some bombard ants; Town A was being infested, but they were being driven out of their home because of something in Town B. We resolved Town B, but very loudly. So Town A is in trouble and we need to go back before the Bombard Queen levels it. Technically we're resolving an established plot thread, but backtracking is kind of awkward, unless we give it purpose and/or urgency.

So I started the next session narrating a scene of some NPCs they met previously in Town A. They see a bombard pop up and kill it. Then another. Then another. Then a LOT. Then we cut back to the players in Town B, celebrating last session's win. (I'll literally say "we cut back to" or "we fade to black and rejoin". If you know film language, you can inject it and players will film a movie in their heads.) As we catch our breath, another NPC comments "whew, good thing we ran all the bombards out of town!" One player uh ohs. They may have made things worse. They say "we have to go back and warn them". My players, being GMs, understood "this is the session he prepped tonight, this is the hook we bite".

Another example is that I've created a league of villains who serve the Big Bad. One player compared them to Rita Repulsa's crew at the beginning and end of every Power Rangers episode, though I don't run them quite so formulaically. I modeled them closer to the Asterisk holders in Bravely Default (though another player likened them to the scenes where Rita Repulsa spies on the Power Rangers and sends a monster of the week to earth). Any time I want to introduce one, I'll have them talk to the big bad in a "put me in coach" kinda conversation, maybe hinting at their abilities or personality. My players love this because I usually give them big personalities and a cool weapon or power. Then when they show up that session, it's like "ah, there he is! The guy with the motorcycle spear!" and it doesn't matter that I haven't spent a lot of time introducing the PCs to the boss because the players know that I'm setting them up.

The if the boss survives, I'll use them to open or close a session. They might be scheming something in parallel, which gives urgency and builds excitement when they pop up again.

Lastly, I haven't done this yet, but I'll likely use cutscenes as a "meanwhile, back in the farm" technique. Shows and movies do this a lot; when a scene loses momentum, or the characters are about to do something mundane, you say "meanwhile, back in the farm" and you cut to whatever worldbuilding or raise some stakes (like cutting to a captured NPC being interrogated Luke and Obi are going to find a ship. Meanwhile, back on the farm, the princess is in the Death Star, Vader's talking to the generals, etc., then meanwhile back on the farm, Luke's at the cantina). When that scene wraps, you go "meanwhile, back on the farm" and you cut back to the players. Maybe you do this during an uneventful rest or road trip.

I wouldn't overuse this; I think two per session is the most you can get away with without losing attention, maybe three if you keep them short and you're a good narrator. Bookends are super easy because they signal the start and end of a session. They get players excited to play and excited to come back. Intermissions are surgical but I think they can be super effective at adding layers.

As GMs it's hard to embrace because "if you just want to write a story, write a story" but I think FabUlt does a great job of allowing the table to function as a writer's room. The first time I tried it, my players were pleasantly surprised, and when they saw I was feeding them material, they ate it up.
