Don't you love that when Zachariah throws classist, fetishistic bullshit at Adam, it spectacularly backfires?
///
Zach almost LOSES Adam with this line. Why?
ZACHARIAH: So you know you can’t trust them, right? You know Sam and Dean Winchester are psychotically, irrationally, erotically codependent on each other, right? ADAM (looks suddenly steely, staring through Zachariah): I don’t know. They said a few things about you. ZACHARIAH (becomes visibly angry): Really?

Zach has misread Adam's sense of class. That nice home that Adam and his mom have together came at a huge sacrifice: their time together.
Adam is, at his core, the son of a single mom. His whole childhood is colored by it, and he's well-acquainted with the inevitably rude/incestuous "mama's boy" taunts it comes with.
This was telegraphed and set up earlier in the episode:
ADAM: You see, it was me and it was my mom. That's it. She worked the graveyard shift at the hospital. I cooked my own dinners. I put myself to bed.
Yeah, Adam "read" Zachariah's taunt for the filth it was.
