Let me quickly say, concussions don't immediately happen, they take a bit of time to show signs of but this is fanfic so anything I want can happen.

Coach:

He cursed as you got grabbed then cringed the hardest he ever cringed as he watched you get slammed and he couldn't do anything about it. He shot it, shouting curses to the zombie as he truly felt furious.

Once it was down he ran over, gently helping you sit up: asking if you are okay while his hand touched your head everywhere. You had this 'out of it' look, just a blank stare ahead so he didn't have to examine anymore and knew something is wrong. He quickly got in front of you, telling you to get on his back now. You were out of it but his hurried tone made you move and get on his back. Though as he got up felt like puking so he was quick to warn you better not fucking puke on him. But with him running and moving around so much he had to end up putting you down, just in time as your food came up. He rubbed your back during it, keeping eyes out for any zombies, then put you back on his back.

Once in a safe room he put you down and gently told you to keep still and recover now; assuring you you are safe in here so take as long as you need.

Rochelle:

She screamed your name as she saw the charger raise you up with ease and slam you right onto the road. Even more so when you didn't struggle the grasp and just hung there limb.

When the charger was taken down she ran over, shouting your name as she fell to her knees and shook you to focus as you kept blinking, frowning. You couldn't look at the sky, it was too bright. So tried to just curl up to her but she pushed you off to get you up, panickedly telling you you have to get up. You asked why so she yelled the zombies but you couldn't follow what she was on about. You didn't have strength to fight her either so she got you up and pulled you along, shouting for the rest to cover you two and arguing to you to at least try and walk with her.

She put you in a house and bandaged up your bleeding head with trembling fingers, whispering it'll be okay. It wasn't even to you really, more telling herself this. She gave your temple a quick kiss, now truly assuring you that it'll be okay then pulled you back up. You were confused, feeling lost and a massive headache, so just followed her without complaint and took the pistol she shoved in your hands as she quickly gathered her supplies off the ground.

Ellis:

He cursed then helped get it off you by shooting every single bullet he could into it. Once it collapsed he quickly ran over, muttering curses under his breathe. He helped you up but you swayed and stumbled so he quickly sat you back down; telling you to take your time. But then he saw the zombies running over so he was quick to say 'nevermind!' and pulled you right up and with him. Each time you stumbled he was quick to steady you, muttering you are fine, then pulled you along again.

When he spot the safe room he cheered he sees it and you will be okay. Once inside he shut it and put you in the corner but you held his hand, looking dazed and scared so he was quick to sit aside you and pull you close, whispering 'hey, it'll be okay, don't worry'. He slouched down the wall to lay comfortable then pulled you on him and held you close, rubbing your back or head gently: assuring it'll be okay. He heard untreated issues like these can develop into mental issues so his mind was panicking but he stayed calm for you.

Nick:

He froze for a second then began shooting the charger, cursing it out loudly then rushed to you. He crouched aside you, pushing you down when you tried to sit up; telling you to stay down. Normally he would pull you up, tell you no time for lying around, but somehow he felt this time was different. So he asked you if you are okay. You claimed yes but it came out slow and unsure. When you covered your ears and let out pained sounds at all the sounds around. Now he was sure something is wrong so he yelled to the rest they got an issue. He slipped his arm under your shoulders and lifted you with a groan, telling you you can moan about this once out of this mess.

He put you down once safe and rummaged the first aid kit, asking no one in particular why the fuck there's nothing for concussions. You insisted it's fine and don't have one but he gave a 'don't even start that lie' look then gave you some pain pills and water, mumbling this will have to do for now. He worried over you for the rest of the journey; always asking how you are and checking up on you after each battle. When you slowed down or looked in pain he was quick to make the group stop and take a break and give you some water and medicine.
