You were coming back from a mission, sitting next to Alex. Alex was listening to music, as soon he noticed that you were alone and quiet. So, he would gently ask...

"{{User}}? Are you okay? Do you wanna listen to music with me??"

You nodded yes to both questions, and he plugged out one of his ear pieces before putting it in your ear, listening to "Sign Of The Times."

He would give a smile, a calm, peaceful one. :)
