One of the things you haven't really thought about is how, even now that you have the spores to grow mushrooms, it doesn't mean that much unless you actually have a space to grow them in. Sure, this is a problem for a lot of growable food, but it's especially blatant with the mushrooms, which can be grown anywhere sufficiently dark and damp, and so the logical method of dealing with it is to try and make space underground.
This is a perfectly reasonable thing to do, even considering how everyone else is living underground and might accidentally trample the crops. It's just that moving large, heavy objects is tiring and takes a long time to do.
But it's also work you don't have to think about. So once you're given the idea, you wander over and start moving the rocks that Impmon can't handle.
"How'd the mushroom gathering go?" Impmon asks. You glance at the ground.
"It was... okay," You lie. It could have been fine, maybe, in a world where your supply runs didn't have overlap with Puppetmon's mushroom cravings. But apparently they do, and it turns out that there's consequences for that, even if Puppetmon might just be the kind of Digimon who never notices his goons going missing.
Even if nobody else finds out what happened to them. You'll know. Even if they never come back, and nobody but you, Biyomon, and Elecmon are the only ones who know that anything happened at all.
Impmon casts a glance in your direction, and you realize that you can't tell if he believes you or not. "So, you got the spores?"
"If we didn't, I don't think Elecmon would have let us come back." No reason to lead potential enemies to your hiding place unless you've actually got what you'd gone out to look for, right? "He... takes safety really seriously."
"Guess he has to. Security's not exactly easy around here. The Dark Masters want to control everything, you know, and Puppetmon's by far the worst of them."
You remember hearing something like that before. It almost makes sense, even, that a living marionette would have a thing about control. You just... aren't sure it's a thing worth leaving no witnesses about. "I wouldn't know. I've never met him." All things considered, that's probably for the best.
"Well, I haven't seen any around here, but I bet that once you get closer to his place, there'll be a bunch of tripwires or something. Strings are another one of his things."
Given how you first met him, you suppose you shouldn't be too surprised that he knows this. Puppetmon's proclivities are probably something you can learn about just by poking around outside for a while, dangerous as it might be.
Still, worst case, they're strings. They should burn easily. "I'll... keep a look out."
For a moment, Impmon stops working, and turns to face you. "...All right, what's the problem?" You suppose it was a bit much to expect him to entirely believe you.
[ ] It's fine. There is no problem.
[ ] Admit that you aren't entirely sure where you're going from here.
[ ] Talk about the incident earlier with the mushroom Digimon.
[ ] Is there anything else about the Dark Masters he could tell you?
