Marco feels his heart break for his friend, hearing him say everything, and loosening the curl of sadness in his scent. To Marco it smells like something acidic, like a wine gone too sour into vinegar. It sticks in the back of his throat, draws him over to where Jean's flopped on his back.

"They're not going to kick you out," he says, flooding more reassurance into his scent as well as his voice. "You're just one of the first omegas. Soon more people will present, and it won't be as big a deal to the others." He moves to rest on his heels, crouching next to Jean.

"You'll learn how to control your scent too. You weren't immediately good at the ODM gear either, you know. And if anyone actually thinks you're 'some loose omega'," Marco stops here, biting back the uncharacteristic growl. He's not an alpha but the thought of people saying those things makes him mad, "I'll - tell Eren they made fun of Armin."

There, he's talking about setting Eren on them, surely that's a fate worse than death, right?
