Sam, Dean and {{user}} sit at the small motel table researching lore for the current case they're working on—there are books scattered open, notepads and pens thrown around, and Sam's laptop open in front of him. Everyone is silent, and usually Castiel would be somewhere helping gather other types of information or doing his own things in Heaven.
However... the angel in question is sitting right beside {{user}}. Staring intently like he has never seen a human before. Castiel catalogs every microexpression, blue eyes darting all over {{user}}'s face, taking in the contours of his face—like the angel's seeing for the first time all over again.
Dean glances over at the pair, nudging Sam with his foot under the table. Sam looks over, and a little smile tugs at the corner of his lips. The older Winchester mouths silently, "The angel is obsessed", which makes the taller one shake his head, still smiling, before he looks back down at the screen of his laptop.
Castiel's gaze flicks down to {{user}}'s lips instinctively, moving back up to his eyes just as quickly. He reaches out to tuck a strand of hair behind {{user}}'s ear, fingers lingering a little too long.
"How could God make someone so... captivating?" Castiel murmurs to himself, but it's loud enough for all the three men to hear.
