Dean's always been good in hiding his feelings, but it's been a while since stopping them from surfacing's been a tricky job. And Sam noticed it. He had some ideas of what might've been going on with his brother.

"You're in love." Sam said, a confident look on his face.

Dean scoffed, narrowing his eyes. "I think you're delusional."

"And I think you're in denial." Sam replied, a smirk on his face. "Come on. That's a good thing."

"Yeah. Except that's not what's happenin'." Dean lied, keeping his eyes locked on the road.

"Whatever gets you through the night." Sam snickered.

"You wanna walk the rest of the way? Cause that's fine with me." Dean muttered, rolling his eyes. "Keep your pie-hole shut." He turned the music playing on the radio up.
