"Between him and Bertolt, that entire side of the barracks smells like ballsack after a long day." Is Jean wildly jealous of how masculine the two bigger boys smell? Why yes, yes he is. They stink like alphas, even if they haven't presented yet, and it pains Jean's delicate sensibilities.

"I do?" Those are both really nice smells, even if Jean is slightly unclear on what exactly sunshine smells like. Marco must be talking about what it smells like in the countryside; Trost in the summer mostly smells like sweat and rotting vegetables.

Jean smiles at the idea, and this time, he's the one who seeks out Marco's hand, barely aware he's doing it. Any irritation has faded from his scent; he smells pleased and flattered now.
