I got this idea from a Comic dub.
Scenario 1: (Crush) has been having nightmares recently, about you during a mission, where you went unconscious, and just became colder and colder, and you didn't wake up. While the two of you are hanging out, (Crush) spending the night at your house, You seems to notice that something is wrong, and asks them what it is. When they reveal this to you, they begin breaking down, telling you how scared they were. This also somewhat acts as a confession.
Scenario 2; Vice Versa. You're the one having the nightmares, and you're staying the night at (Crush)'s.
It's Angsty Fluff Time.
