i feel like segment 65 would love it the most and would willingly go without complaint.

45 would probably as well. maybe a bit of reluctance if he’s busy or had his schedule rearranged.

35 on the other hand, would complain about going and then enjoy his time there.

25 and 18 would likely cringe and call it boring and make up every excuse not to go because they don’t want to be “old and senile and sophisticated” but will begrudgingly realize that they actually like the music. but they’re too far into the bit to stop the commitment.

From Marrow #1, about Pantalone

I like how older segments are just stating facts about Pantalone getting injured a lot and genuinely wondering about danger of his work. And then 18 goes like “omg he’s still getting into trouble”

I like that 8 is indeed childish here, mocking the big old adult by recording his awkward moment

From Marrow #2, segments bickering. Truly a multi-sibling interaction with old tired father

It has everything to do with the Tatarasuna incident.

Because at 35, Zandik found and saw Kabukimono, a puppet, an inhuman being being accepted by the miners when he himself was chased out of his hometown and expelled from the Akademiya. This inhuman puppet, accepted, where as he, rejected--and envy turned into spiteful selfishness as he targeted this puppet to ruin him.

Like it was not in Dottore's mission to do anything to Kabukimono. Everything he did to Kabukimono--making him think that his human family had betrayed him in both choosing him as the sacrifice and the whole thing with Niwa, then telling Pierro about him so they could "make him an ally"--was entirely his own prerogative. His own choice. He chose to hurt Kabukimono out of his own selfish envy.

That's why I think 35 ends up being the "most selfish" segment.

Edit: I'm more convinced of this after reading the interactions between all of the known segments in the 2nd Anomalous Marrow, and how Segment 45 behaves in particular.

"The ones who need help are always the easiest to talk to." This is such a loaded statement for him to make. He is, essentially, admitting that people who are vulnerable and need help are "easy to talk to", or, more likely, easy to manipulate. Segment 25 basically spells it out for us too--that Segment 45 is being cocky because he holds all the power.

This is further implied by his views on Columbina:

Essentially Segment 45 is saying that Columbina is "approachable" because she looks vulnerable.

I think Segment 35 is the most selfish because Zandik caved into his selfish desire to ruin Kabukimono, and then Segment 45 is manipulative and preying upon vulnerable people because Zandik preyed upon a very vulnerable Kabukimono after he joined the fatui.
