SPOILERS for The Magnus Archives through season 5!
I think it says so much about Jon as a character that he went into the coffin after Daisy.
She kidnapped him, threatened to kill him, held a knife to his throat, and he still went into the Buried knowing that he might not make it out in the hopes that he could save her. On top of this, he attempted, more than once, to cut off his own fingers, and when that didn’t work, he willingly had two of his ribs ripped from his body.
I’m sure this is a commentary on how low his self-worth is at this point - his pain is irrelevant because he’s a monster. His entrapment in the Buried wouldn’t matter because Daisy’s life is worth more than his. But I also think it shows how much of a good person he is.
He went into that coffin, knowing he might never come out, for someone who he could never forgive and who would never ask him for that forgiveness. A lack of self-preservation instincts doesn’t fully account for an action like that. He did it because it was just the right thing to do.
I also think it’s really fascinating that, out of all that he’s been through, that specific incident is what scared him the most, though my little analytical brain hasn’t been able to parse out why just yet, so if anyone has any thoughts on that I’d love to hear them.
Anyways, I don’t think this really gets across how strongly I actually feel about this specific series of events, but yeah. Jon is by no means a hero. But he cares deeply and he’s so intrinsically good and I think that’s enough.
