4, 5, 16 for both Talyn and Rin :3
A crying Rin is an aggressive Rin. She'll lash out, yell threats, growl or roar with a cracking voice. There'll be lots of rubbing at her eyes because the tears just freeze and slowly build up to obscure her vision, which just adds to the anger and frustration of feeling An Emotion for her.
The more intense the crying, the more intense the aggression. It might start with just some half-hearted threats, but get the tears flowing and there will be screaming, property damage, grievous bodily harm. She doesn't handle the loss of emotional control which comes with a good cry well.
Talyn is the exact opposite. She'll retreat into herself, make herself as small as possible. Bottle it up. Keep those emotions under control so you don't hurt anyone. At best a Talyn cry might be a few streaks of tears and a forlorn look into the distance. At worst it's hunched over, curled up, and horrible, choking sobs tearing their way out of her throat.
Don't try to comfort her. It won't end well for you. She knows this, and it just makes it all the worse.
Rin either insists she isn't tired, or complains about how tired she is. Depends on the current company. The usual flair and swagger she usually puts out is replaced with entirely non-flashy, terse and efficient actions. If someone presses her about it, she'll get angry, but a slightly more impotent angry than usual...unless you *really* push her.
This might very well be the only state in which you see Talyn relaxed. She'll desperately try to keep herself composed and stay awake, but the sleepier she gets the more the tension drains and she steadily turns from a rigid beam of a person, to a puddle, leaning and slumping on anything or, if sleepy enough to not realise, anyone nearby.
