Do you ever just think about how in Batman The Knight, Bruce mentions they promised to not use guns and yet Bruce is the first one to shoot Luka to protect Khoa? Especially considering his small flashes whenever he had to use guns even at inhuman targets? And he still did it?
YES!!! Yes, I do!!!
I went through this specific issue recently and i have so many thoughts, I hope you don't mind me using your ask as an excuse to ramble :)
Bruce was having such a bad time in this issue it's not even funny. Luka just decided to kill the only constant figure in his life at this point, his partner, his bestie, his boy crush, his only companion, and just expected him to sit and watch while he shot him right in front of his eyes, like, bro, right in front of the traumatized by loved ones being shot in front of him boy??? WHY
And of course that happened after months of him relieving this particular trauma repeatedly on account of having to use guns and interact daily with a guy who, bc of his past career, he couldn't help but compare to his parents' murderer. Why not, after all. Just marinate him a bit before going for the kill.
Obviously, Bruce couldn't let Luka just kill Khoa, so he takes the gun, and he doesn't even kill Luka, but taking that shot was such a difficult thing to do in such a stressful situation in which he's clearly relieving his biggest trauma. And like, sure, he made his promise to Luka, but more than that, guns are forever associated with his parents death and their murderer. Bruce very much can't use guns on real people without shaking, trembling, throwing up, yk, feeling like he's putting himself in the shoes of joe chill and feeling so intensely guilty. It’s really his last resort - if it was Bruce’s life that Luka was threatening, he might even have let himself be killed in order to not have to use the gun.
However, since the universe is not over with him yet, and still has some ideas about how to make his day worse, it decides instead to force his hand by making Minhkhoa be the one being held at gunpoint. Thus, Bruce does take the shot anyway in the worst way possible and in the worst situation ever, and literally the only thing that could've been worse would be making him kill someone, so of course,
THEN
MINHKHOA TAKES THE GUN
AND SHOOTS LUKA RIGHT IN FRONT OF HIM
MAKING SO THAT BRUCE'S SHOT REALLY RESULTED IN SOMEONE'S DEATH
ONCE AGAIN
RIGHT IN FRONT OF HIS TRAUMATIZED EYES
and as if this wasn't enough
HE THEN POINTS THE GUN AT BRUCE
Honestly his biggest crime, I don't care about the murders and other felonies, this moment right here is the only thing he ever did wrong.
Like, can you imagine the level of brain damage bruce was receiving that day?
Khoa went from loved-one-about-to-be-killed to being the one walking on joe chill's shoes. His range, honestly. No wonder Bruce got so mad and then so heartbroken. Crying his eyes out, literally hugging himself. The saddest, most traumatized boy ever
Anyways, bruce still misses him, even after all khoa put him through. Or, as he says, he misses who he thought he was. After their first breakup khoa's image took a lot of damage - bruce really starts to wonder if khoa wasn't just a monster and he was the only one not seeing it. He thinks minhkhoa is sabotaging him, and that he might have killed alfred and his ex-girlfriend.
But of course nothing of this it's true and Khoa manages to undo some of the damage to bruce's opinion of him by trying to warn him about the guy actually sabotaging and trying to kill both of them (he also almost dies in the process, which i'm sure made him seem extra harmless and babygirly to bruce), so i guess that was enough to take away the thoughts of khoa being very likely to kill him one day.
He also offers a justification for the two murders he committed (Luka and master Ouahbi - honestly, what's the deal with all those criminals/ex criminals being both so good at diagnosing people with psychopathy and hating them so much????), and it was good enough for bruce, i guess? Tbh, he was mostly just trying to not think too deeply about it, 'cause he just wanted to have a little more time with him so badly. He would do so many things for khoa, and forgive him for so much stuff. HOW COULD KHOA FUMBLE HIM SO BADLY-
One thing I think about a lot is how in btk #7, bruce’s broken heart is addressed - he only references his trauma with his parents death in the issue, but the last issue ended with him saying his heart was broken bc of khoa so we can infer that he’s thinking about what happened between the two of them too. I find it interesting how this seems to be bruce’s way of dealing with khoa - he doesn't talk about him. Dick mentions it in Batman (2016) #104
And bruce never says a word about what happened between him and khoa to zatanna
I wonder if this is his way of keeping khoa with him. As he says, his heart never heals bc he doesn't let it - and so, he never talks about khoa, he only talks with zatanna about the loss of his parents, and he tells dick some of the bad khoa did to him, but doesn't delve into how important he was to him, or the good times they spent together, or how willing he was and still is to forgive him (tho he ends up showing him this part anyways when he goes to ghostmaker to ask him to coparent batman inc. with him when he first started it). He tells their story in a way that makes it seem like their separation didn't affect him negatively at all - dick only realizes bruce still misses him bc of his super powers of seeing right through bruce’s emotional barriers. But bruce keeps refusing to talk about khoa, or adress the ways in which he is still hurting, so he nevers gets better, and thus, khoa is still with him in a way, if only in wounds he left behind.
I also think bruce focuses a lot on everything bad khoa did to him and tries so hard to not even think about the good parts of their relationship bc the truth is, in his heart, the good outweighs the bad by a lot. Which is the reason why khoa barely has to do anything to win him back every time he comes back - bc despite everything, bruce has always been way too willing to forgive him for everything, and all he really has to do is to come back, and be willing to stay for a little while longer.
