Your tags, tho. I'm having gentle feelings for them.
I love thinking about the Corruption, especially in relation to Martin and it being him that Jane targets. And yeah, sure, he was there in Vittery's basement and Tim and Sasha weren't, but he’s also a person who, as Elias meanly points out like a big meanie, often shows great devotion and loyalty to people who don't really deserve it (sorry Jon, you'll get there, but at this point you're still a jerk).
When the people who are supposed to love you unconditionally (ie your parents) not only put conditions on that love but ones you're never going to meet no matter how hard you try, it's gotta warp your idea of what love even is. Can't really earn someone's love if they already hate you for something vastly out of your control.
Obviously The Lonely comes along and Martin chooses isolation, but there has to have been a point when he was alone in his flat for two weeks, assuming that no one had noticed he was missing or if they had they didn't care enough to check on him, where he heard The Corruptions song and thought it was for him, thought it sounded beautiful and thought it would be better to be loved by something horrific and poisonous than be loved by no one at all.
