i don’t think Bruce has a favorite kid, at least not cognitively. i think he does favor one or the other but it really depends on what time and state everything is in. no, instead i think he has a specific TYPE of favoritism for most all of them.
with Dick: that’s his first child. that’s his first robin, and the one that had surpassed him by far. they butt heads with because they’re both grown with different ideas about how to do things, but at the end of the day he looks UP to what Dick has managed to create. Dick is his hero, and his greatest success. he can’t imagine Dick ever truly letting him down. he also struggles so hard to verbalize any of this to Dick because Bruce is Bruce and because of the arguments they’ve had in the past, but Bruce takes every opportunity to gas Nightwing up and that’s canon fact.
with Jason: people often write it like Bruce lets Jason get away with everything which is… kinda true? but also not? people write it the opposite way too, where Bruce never lets Jason have a single break which is?? sometimes but?? not exactly?? lmao. inconsistent writing in DC? gasp. anyways, it comes out to result in a complicated mix of those things. Bruce feels an immense amount of guilt for Jason’s situation, how he’s turned out. he feels responsible for Jason’s crimes in a way he doesn’t with almost anyone else because to him, BRUCE is why Jason has been pushed there. also he sees his kids as an extension of himself in some ways (yeahh not too ideal or very healthy… Bruce should go to therapy about that… lol as if) especially when they wear his symbol this mistake-type responsibility is on TOP of that stuff. so on one hand he’s harsh because he’s trying to “fix his mistake”, in a way trying to hold Jason back because he kind of takes on even more responsibility for him than he does with his kids on the regular, but he also lets Jason off and gives him chances again and again because that’s his son, damn it. and in the same way that Bruce is too harsh because of his perceived responsibility, he is also light because of it being not all Jason’s fault, but Bruce’s. it was Bruce’s failure that brought them here. cue the gaps, Bruce has a Guilt Thing. and it means Jason gets to come back and try again as many times as he wants, and gets to fuck shit up and get yelled at and iced out, but also to come back. every time. oh and the little stuff? Jason gets away with it so bad because it’s a miracle if he’s even remotely listening to the shit Bruce asks of him. small potatoes in comparison to the murder.
with Tim: after Jason’s death, Bruce wouldn’t have been able to deal with Tim dying too. this led to intense training and strictness, which Tim understood. Tim, to Bruce, is the kid he’s prepared the absolute best he can. it is because of this he can put too much on Tim, trusting him and relying on him. Tim was the one with him in his darkest times, and he wanted Tim to be prepared for everything he and also Jason never were. this leads to fucked up shit like Tim’s 16th bday. look it up, it’s fucked. Tim’s independent and trustworthy, but that’s not what he always needs/needed and Bruce didn’t figure that out in time to address it right. Tim is also so much like him sometimes, right up there with Cass and Damian, though for different reasons. he fully expects Tim to be the next World’s Greatest Detective. he respects Tim kinda like how he respects Dick, but like somewhat in an anticipatory way as well as the regular proudness Bruce has for most of his children (sorry Jay he loves you but he is NOT proud of the murder lol) slash vigilante mentees. i feel like i could have written this one better but i have so many feelings abt Bruce and Tim that it’s ironically harder for me to find the words for describing it like this lol.
with Cass: i know less about his relationship with her, but she is so much like him in so many ways. they butt heads the least because she gets him. she and him are both devoted to the Batman mission, are familiar and intimate with it in ways no one else is. i wish i had more to say and i will someday, but that’s it for now. #CassShouldBeTheNextBatman, thank you very much.
with Steph: not his kid, so i’ll keep this brief, but i almost think he wishes Steph WERE his kid because then he’d be able to order her around easier and he really wishes he could because he’s terrified at the idea of her dying for real. he sees so much potential in her and has tried to cultivate it, but her resistance to listening to him or treating him as an authority really pisses him off sometimes because he wants so badly for her to GET it so he can keep her SAFE. she doesn’t get much of a favoritism type or whatever because she’s not his kid, but she does “get” to shrug off his authority a lot. the daughter-in-law, regardless of if she’s actually dating anyone in the family.
with Damian: i also know woefully little about their dynamic as it sits now, but i’ll give it my best shot. Damian is so young and he’s suffered so much. Bruce wants to give him room to grow and fly but, sometimes, them being so similar (personality wise: stubborn, uppity, particular, harsh) can lead to their squabbles. he sees in Damian, ironically, someone he could have become if he’d been pushed a darker way at the right wrong times. this is why he lets Damian off so much at the start. he knows Damian can be better and he sees that Damian wants to, deep inside. it doesn’t hurt that this is his bio kid, which is so new for him. it doesn’t make Damian better than the others, but it trips Bruce up. he’s nowadays so, so proud of how much Damian has grown past the murderous assassin he once was. it gives him hope.
with Duke: slay me where i stand but i also don’t know too much about his dynamic with Bruce. i know his backstory now but like nothing about his actual canonical relationships with the batfam. so so so sorry. i do feel that Bruce is hesitant in some ways of overstepping because Duke’s parents are both still alive but that’s like all i’ve got. we’re supposed to be talking favoritisms, so i suppose Duke would get recency bias. new kid status. maybe. idk. sorry. someone please fill in for my deficiencies, i’m still catching up with slightly older comics.
this is what i’ve gathered from comics and such; i feel strongest and most secure in the first three, the rest is mainly me speculating and brainrotting. it’s like it deteriorates in canonicity/strength as it goes on, i’ve noticed. lmao. maybe sometime i’ll ramble about the kids’ side of things/perspective on all of this. PLEASE correct me if i’m wrong somewhere, i’m new and i love learning. or just give me your takes because i WANT them!!!
