How The Divergent Characters Would React To You Being Injured/In Pain (Headcannon)
Tris: she would rush to you, assessing your vitals and pain scale. She'd be really good at distracting you from the discomfort and assuring you (quite fiercely I'll add) that everything is going to be okay. Wouldn't leave your side and would do anything possible to help you (aka her Abnegation is showing)
Four/Tobias: like Tris, he'd run to your side, ready to help you. I feel like he'd keep his demeanor much calmer and his emotions to himself but his disposition to help you would be noticeable. Also wouldn't leave your side, and probably wouldn't sleep or calm down until he knew you were okay.
Peter: Gonna be real with y'all, Peter would probably faint or nearly faint at the sight of you injured. He'd try to keep his hysterics as under control as he could but knowing him, he'd probably snap at anyone and anything. Anxiously pacing, rushing to your side when you ask him for something\wake up. Once you start recovering, he'd start cracking jokes like usual.
Christina: probably the only one to be really soft and caring while still trying to keep a brave face on. Would probably break down at some point, would sleep next to you, and hold your hand during the day. She would also be one of the only ones to be honest with you, being raised Candor.
Will: Will's definitely the one to cry or emotionally break down at the vision of you injured\hurt. He'd do anything, physically and emotionally, to ease your pain and bring back some level of comfort. Wouldn't leave your side, sleep, or probably even eat. Caresses you while you're out/asleep and tells you about interesting things he saw that day, in hopes that you can hear him.
Eric: I don't like Eric but fine. Let's be honest, he'd probably be an asshole but with a certain level of worry towards you. Would probably get really frustrated with everything around him, unable to deal with his emotions. (bleh, like I said, I don't like him enough or at all to write him sorry)
