This is Allura exiting her cryopod during episode 1:
And this is Coran:
Allura eye’s are closed because, in this scene, she is literally ‘waking up.’ We know that Alfor knocked her out before putting her in the cryopod. But Coran’s eyes are open from the very beginning. This means that he willingly, consciously, stepped into the cryopod. Which raises a new question: Did he start the cryostasis process himself, or did he have help?
Judging by his solemn expression, controlled posture, and downward gaze- I’d wager that the last thing Coran ever saw was Alfor’s face.
