What would that look like for you? I love PIC, and I love how much more lived-in it feels than Berman-Era Trek. DS9 felt the most lived-in of the previous shows to me, and I find myself wondering what it would look like today, in HD, with all those diverse aliens we delved into deeper in the series.
But, no, seriously, the O’Briens divorcing goes back to the many deaths and tortures and trials of Miles in the series. He’s not even “our” Miles (he died of radiation poisoning) but one from a parallel universe. Another one we thought was him was actually a replicant/synth who as killed before being activate to assassinate a peace delegation. Miles convicted and sentenced to decades of barbaric imprisonment where he served out his term and murdered his cell mate over a misunderstanding. He was abducted, beaten by Cardassians, had a tooth yanked out, and set up on a planetary show-trial to be executed. Other stuff.
