I'm not sure if anyone has pointed this out, but in all the months I have been in the poolverine fandom, I haven't seen anyone (as far as I'm aware) entertain or acknowledge the possibility or implications of Logan being the one to bury all of the X-men and the rest of the mutants that got killed in the X-Mansion when he found them after coming back drunk from a bar. Like imagine the angst and whump potential of it all, the shock he first felt when he noticed the signs of a break in, then the horror as he sees the bodies, the grief, sorrow and pain crashing down on him as he sees that no mutant survived and everyone in the mansion is dead, his guilt as he realized how he could have been there to protect them and how he blames himself for not being there, for abandoning the people he had grown to care for because he could never allow himself to be part of anything. Imagine the heaviness in his chest as he realizes the only thing he can do for them now is to bury them, each and every single one of them. Imagine how much time he spent in the mansion grounds, digging a grave for each mutant and carrying their lifeless bodies to their final resting place, how he holds their body in his arms, trying to tell himself that they're just asleep yet his sensitive hearing picks up no heartbeat. This is possibly the only time he has ever held any of them close in his arms. They're gone and dead, because of him. He tells himself he's used to it by now, he SHOULD be used to it by now, being the one to bury those he loves. But with every body buried, every graved marked, he doubts that idea. Sometimes, there's not even a body for him to bury or a body whose name he could mark. He grieves that he hadn't been able to know the rest of them well. He finishes by nightfall, X-Mansion now turned into a cemetery, a grim reminder of Logan's failure. The physical embodiment of his title as the Worst Wolverine in the entire multiverse. He tries to deliver them justice, avenging them by hunting and killing those who killed them, he lets his rage and violence win over his grief and starts mercilessly killing, turning humanity even more against mutant kind. Yet, his rage does not linger forever. Eventually, he comes back to the mansion with nothing but a graveyard to welcome him. All his anger have left, his only solace is at the bottom of a bottle. Every night, he stays in the mansion grounds to feel taste of whiskey burning down his throat. Every night, he regrets on what he has lost. Eventually, he leaves and moves from place to place, bar to bar, trying to forget. He can't and he never will. It eats him up inside no matter how many glasses he has downed.
Now, he is with Wade, his pain and loss still lingering but being with his current little family is enough to lessen the hurt. Still, he fears he'll have to bury them too. Yet, he lets his fears be dampened by mouthful merc who took his heart, he assures himself he'll never abandon his family again, that he'll be there. He lets his love foster and his fondness grow. Perhaps, he thinks, one day he would have to bury them, but at least they'll have the knowledge the he'll bury them after loving them enough. Perhaps, he thinks, one day, someone would love him enough to bury him, too.
Look, I just think this concept should be more explored in the fan works. If there are works that did, please send me a link! I would love to read them.
