I think there's a lot of triage in the way the jedi handle the events of the prequels, and it just gets more and more pronounced as the movies go on. In tpm you see Qui Gon make a series of quite utilitarian decisions within his mission, reflecting the wider backdrop. Even the council changing it's mind about Anakin's training can be understood this way; the evidence of a sith master (who would presumably be in the market for a new apprentice) makes training him themselves a matter of priority, despite their previous assessment of him. At the beginning of aotc they are advocating for diplomacy, by the end they are using the illegal army they were highly disturbed to find to hunt down the separatist leader, previous concerns superceded by the urgency of the now. If they can just get dooku and attack the droid factory now, maybe they can nip this in the bud. The rest can wait. This is an established pattern by rots. They know there's a sith master in the republic, they're keeping an eye out, but they've got to deal with the one they know about. They know palpatine is dismantling the republic bit by bit, but again, gotta get the seps on the backfoot before they act against him. Gotta carry out that coup before they can hold an election. Gotta get the immediate problem under control before moving onto the next one.

Sabine and Rebel are still on the search for Ezra

We were doing an activity where the kids got to make a playbill for a musical about themselves and all the other kids were like “character list: mommy, daddy, me, my brother, my best friend” “scenes: I get a puppy, first day of school, my baby sister is born”

I believe this is less detached than you think, he is emotionally abusive at best. He is doing this intentionally. He is attempting to gaslight her. She revealed something exploitable about herself, and he's exploiting it. Abusive men start with "small" arguments that seem impossible to have as a rational adult, and so the reaction from the victim is usually "I must be missing something...maybe if I explain." This is the purpose, to start making her feel detached from reality. This is why they come on reddit to ask if they're overreacting - his abuses are working. He has slowly moved the needle to the point she losing grasp on what is rational and true. I can't be sure, obviously, but I would bet the pillow thing is just one of many, many, many things he is doing to slowly skew her reality.
