i'm confused by this question, but it's because to me, their interactions wouldn't really change...? post-ruina interactions are mostly just "they start to all feel more comfortable being around each other if they weren't already" so i don't really think that's going to impact how chesed and binah interact with each other because they already have an established manner of how they interact with one another versus other patron librarians who never really developed a specific dynamic with binah prior (like netzach and yesod)
