Cal walked into the ED the next morning to be met with Zoe, Charlie, Lofty and Robyn having a conversation. The minute they saw him the conversation went quiet. Their reaction when they spotted him gave him an uneasy feeling in his stomach. Nervously, Cal approached them.

"What's happened?" Cal asked.

All four of them turned to him with sad glances. It was Zoe who spoke for all four of them.

"There's been an RTC. 4 incoming patients, one of them critically injured."

"And?" Cal said, not liking where the conversation was going.

"The critically injured patient is Ethan." Zoe finished.

Cal felt his knees buckle beneath him but, thankfully Charlie was there to stop him from falling. His breathing was becoming laboured and sensing Cal shouldn't be there when the paramedics arrived with Ethan Zoe instructed Charlie to take him to the staff room. Cal refused to move. He wanted to treat Ethan. Zoe immediately shook her head. He knew the rules. No family members were allowed to treat patients. Reluctantly, Cal let Charlie lead him to the staff room. Once Cal was sat down on the sofa, Charlie sat down beside.

"This is all my fault. It's my fault he was driving."

"How is it your fault?" Charlie inquired. "He was coming to work."

It was then Cal shook his head.

"No, he wasn't, Charlie. He was getting away from me. That's why he was driving. He was driving away from me. I've messed up big time this time."

"You haven't, Cal. Ethan just needs time alone. Once he's come to terms with what has happened you'll be able to sort things out between you."

A thought suddenly hit Cal. What if Ethan had been the one to cause the accident? What if Ethan had lost control of the vehicle because of something that happened to him? All these questions racing through Cal's mind only brought more worry. Could Ethan be showing early signs of Huntington's Disease? It would make sense since what had happened to Ethan over the past couple of weeks. It was certainly out of character for him to lose his temper, but for him to lose his temper with a patient was so unlike Ethan. Even him quitting his job, a job he loved doing and considering moving to Australia was out of character. Cal immediately shook the thought out of his head. He didn't want to think about Ethan having Huntington's. For if he did, it would mean Cal would have to be there for him. Something Cal didn't think Ethan would want at the moment. Charlie sat beside him saw Cal was lost in thought. So being the friend that he was Charlie inquired if he was alright.

"I'm not being paranoid or anything." Cal admitted. "But, what if Ethan was the one who caused the RTC? What if he lost control of the steering wheel? Like because his hands were shaking?"

"If I think you talking about what I think you're talking about there is still a chance that neither of you have it." Charlie responded.

"Yes, but there is still the possibility that one of us might. What if Ethan has it? I mean I still haven't got the blood results back but, what if, Charlie? He can't go through it alone."

"Let's say for the sake of this conversation that your brother has it, and that's a big if, then he won't go through it alone. You'll be there for him every step of the way."

"What if he doesn't want me to be there? What if he pushes me away?"

"Cal, we all have 'what ifs'. But, this isn't a what if. Ethan's been involved in a major RTC and he's going to need you to be there for him when he comes in. It won't matter if he pushes you away because he doesn't mean it. As much as he's angry with you, he still loves you like you love him. And if he does try to push you away you're not going to because you know he needs you. You know he still needs his big brother and you need him too."

As Charlie was finishing giving Cal some sound advice the door to the staff room opened and both looked up to see Zoe standing there.
