One trope that i find weird is that during batfam reconciliation fics, the batfam members use alfred as like the big red button to bring jason back, but i feel like that wouldn't actually work. at all.
Jason would HATE alfred after everything he did after he died. Canonically, it was alfred that made the "a good soldier" memorial case, bruce wanted it down but alfred insisted he keep it up, he was the one that gave tim the Robin suit THAT JASON DIED IN, and drove him to save batman and nightwing with NO training at all. He also helped keep up all the "jason was always doomed for a life of crime, and he was an angry child that got himself killed" narrative that was spun after DitF. Alfred pennyworth is batman's biggest enabler, and has stood by while bruce did all his bullshit, such as the whole UtRH arc, and RHatO #25, where he said that it was inevitable that jason would go back on the whole no killing agreement.
Alfred may care for all of Bruce's children, but his only grandchild is damian, as shown when he made him robin behind tim's back( the whole "dick made damian robin" thing is just to add to tim angst. Dick was infact against that whole shitshow). If it doesn't benefit bruce, his pseudo son/employer and landlord, he wouldn't give a fuck.
It's basically impossible to write a reconciliation fic at all without completely rewriting characters, especially jason and alfred. Jason believes that batman's mission is flawed and useless since he doesn't permanently stop crime, so he'd never fully give up killing, the whole reason there's a rift between him and bruce, and alfred isn't this doting grandfather that always sides with his grandchildren and bakes cookies and makes tea.
Also, one major thing the fandom forgets is that alfred is canonically a shitty father to julia, his bio daughter. He abandoned his own daughter for the waynes, he'd never prioritise bruce's children over him.
