The thing is that Haru's right, he's really right, and Julien - wants to be able to do things. The most things. There's an archetype, right, of like, crazy vegans and people who think trees have souls or are really really worried about bugs, who - are sometimes just correct about things, depending on the category, but what matters is that they feel the presence of a horror at a scale beyond comprehension, one that humans are complicit in, and then when they try to talk to other people about it, they do it accusatorially. And then everyone hates them. And then they can't get anything done. (He pets Haru.) Because their conviction turns into self-righteousness and they can't compromise on that enough to care about the results.
Julien really, really cares about the results, here.
So - he knew already that he didn't want to be miserable forever and fail to do any things. It just seemed appropriate, the first time he encountered proof that dungeons are more like animals or maybe even people than trees, to take a good, he doesn't know, maybe sixteen-to-fifty hours to mourn about it. But he has a chance to set a course, here. This is the starting point, and while he could probably correct onto a better trajectory next time even if he blunders today, he doesn't have to blunder today on purpose just because it would make him feel better by feeling worse.
(A reminder from last week shifts into focus - there's value, sure, in commiserating with someone, of sitting next to them and feeling their pain, in grieving - but you don't get to torture someone just because they're you. And sitting and grieving is for things that have already happened, not for things you can do something about. Otherwise it's just laziness.) (....Kind of. It also isn't good to fall into the trap of beating himself up for feeling bad while being mind controlled to feel bad. But he's trying to motivate himself, here, and he'll take his boosts from frame-switching where he can get them and sort out the rest later if he needs to.)
Okay. Cool. He already wanted for this part to be over with as soon as possible; it was just that the situation felt too oppressive for him to do what needs to be done, which is to make out with Haru. Everything is - still wildly not okay, but he can pretend. This dungeon is already dead, its fate is already sealed, and the only question is what can he learn from it. The less he learns from each dungeon the more dungeons he'll need in order to know enough to maybe save them all. (That's such grandiose thinking - he's not going to be able to, he's just going to be burdened with the knowledge of their suffering without being able to do anything about it - but - anything that he can accomplish, this logic still applies to. Hup.)
