He had no idea how many energy drinks he had drank today, all he knew was it didn't matter. He was going to give the patients the best treatment they deserved so he drank another one. As he was finishing his fifth or sixth or maybe eighth he heard someone call out his name.

"Ethan." Lily said as she stood beside him. "Don't you think you've had enough of those for one day? You need a break. Why don't call it for the day and head home?"

"Because my shift doesn't end for another 4 hours. And I don't need a break. I'm fine." Ethan told opening yet another can.

Lily shook her head grabbing the can from his hand as she did so.

"Lily, can I please have my drink back."

"No."

"Fine. I'll just get another one from my locker."

Ethan turned around but, was stopped by Lily when she grabbed his hand.

"You're not going to have another. You've had a tough day, Ethan. You need to rest."

"And I've told you I'm fine." Ethan yanked his arm away from her grip.

Before Lily could protest Ethan walked away from her and headed towards the staffroom. Lily followed behind knowing what he was going to do. Reaching the door before Ethan, Lily stood between the entrance and him.

"Could you please move out of the way."

Lily didn't answer. She just stood her ground.

"I said move." Ethan snapped.

"I'm not going to move until you stop drinking those energy drinks. You know what damage they can do."

Ethan didn't even bother arguing with her. He just walked away again. Pushing the doors to RESUS rather roughly in just stood there in the middle. His day couldn't have got any worse. Now lying in front of him was a death he could have prevented. He felt his knees buckle beneath him. But, before he had time to hit the floor a pair of arms wrapped around his waist.

"It's okay, Nibbles. I've got you." Cal whispered to him as he felt his little brother shake in his arms.

Ethan continued to sob. Cal didn't know what to do so instead he took Ethan away from the room and to the staffroom where they could have some privacy.

"Everything's going wrong." Ethan choked. "This is all my fault. "

"No." Cal said firmly.

"Yes, it is. It's my fault that patient died. My fault I missed the signs of Olivia being abused. I should have given them my full attention, but I didn't and looks what happened."

Cal grabbed Ethan's face in his hands.

"Look at me, Ethan. This is not your fault. There is only so much you can do. "

"I've should have seen the signs. I should have reported it."

"You're a doctor, Eth. Not a social worker or the police. It's your job to treat the presented injuries and then let the other services deal with it."

"It's still my fault. Even if it's not directly my fault."

Ethan suddenly felt faint. He began to sway and Cal notice Ethan was not focusing. Cal caught him just as he fell forwards into his arms.

"Ethan?" Cal shook his shoulders.

No response.

"Can I get some help in here!" Cal shouted through the door.

Connie rushed in along with Rita.

"What happened?" Connie demanded.

"I don't know. He just collapsed." Cal explained.

"Right, let's get him on the floor." Connie instructed.

With Ethan laid out the floor Connie checked his eye movements.

"Well, his pupils are dilated and reactive. But, he's severely dehydrated. We need to get him into RESUS and hooked up to 2 litres of saline." Connie said as Max entered with a trolley.

Rolling into RESUS Ethan began to come round.

"Nice to see you back with us." Connie said as Rita hooked him up to the saline drip.

"Where am I?" Ethan asked groggily.

"In RESUS."

"Why?"

"You collapsed on me, Eth." Cal explained to him.

"Here, Ethan. I need you to breathe through this while we get rehydrated." Rita said to him, placing a mask over his face.

While Connie and Rita were checking his vitals Ethan beckoned Cal to come closer to him.

"Yeah, what is it?" Cal inquired.

"What did you want to talk to me about?"

"Huh?"

"You texted me. Said we needed to talk."

"Uh, about that. Well, it can wait until you get better."

"Really?"

Cal nodded. He knew now wasn't exactly the best time to break the news to his brother. Not when he was already so stressed.

"Well, we'll talk when we get home, okay?" Ethan said.

"Uh, sure." Cal responded.

"Good, because I've need to tell you something too."
