They sure are some very messed up gears!
It’s a bit as though most of his mind was struck head-on with some sort of overwhelming force. Half of the gears are entirely out of contact with each other, knocked out of place and spinning uselessly with no purchase. One of the key drive-shafts looks almost melted, warped and useless.
Nearly all the still-functional pathways run through a different drive-shaft; previously more peripheral to his mind, but now supporting everything. Without context, it’s hard to tell at a glance what that area does, but it’s in the region that corresponds to basic, primal emotions.
In this case, plausibly rage.
More subtly, but quite noticeable after she’s acclimatized to the distracting damage, there are copious signs of very heavy shunts, probably corresponding to what Melody was calling “blocks”. They scaffold the most-affected areas, redirecting some of the pathways that would otherwise end in pointlessly-spinning disconnected gears.
...And there’s something else, too. Something less familiar. The patterns of his mind are - oddly constrained, in a way that seems neither intrinsic to him, nor done by a Mindhealer. The most comparable metaphor that her Sight reaches for is...magnetic ball bearings? They’re small and tucked in amidst the rest, hard to see directly, but the effects, once she’s remarked on them, are much clearer. In some places they appear to hold together badly damaged paths, taking some of the load from non-functional gears. In other parts, it’s more like they’re gumming things up, or even blocking some routes entirely.
