"Your-" he starts, initially confused — but quickly enough, realization sets in and he looks at her with a dawning understanding blooming across his expression. "That's what that was. Back at the barracks."

A beat, and then what she calls it hits him again. He can't help but mildly judge her, "Incognito Mode? Really?"

As though he has a single leg to stand on when it comes to naming things. He's the worst.

Whatever. Not gonna dwell. Instead, we're gonna focus on the other half of this conversation. This is a prime example of a teenager being a little shit. Brace for a counter-attack of Dean going full embarrassing Dad mode and leaning way too hard into a topic he knows most teenagers will be immediately repulsed and cringed out by.

Time to call her bluff.

"But for your information, no. Angels don't carry diseases. But you know who does? Teenage boys. Or girls. Whatever floats your boat. The point is, always use protection. Also, get tested. Have your partners tested. Have you seen Nadine? I bet she could run a diagnostic for free..."

He is fully prepared to go on and on if she doesn't stop him.
