The moment Cerys had rushed off to the loo, Rose couldn't keep the worry from her face. There were a few times in which her best friend had a reaction as such and they never ended well. Instead of following after her like she wanted, Rose remained at the table. Although the Doctor had tried a few times to engage her in some form of conversation, each effort was ignored. Rose was just too worried.

When ten minutes had passed without Cerys returning, Rose got to her feet and closed the distance between herself and the bathroom. She could hear the Doctor following her but paid little mind as she knocked on the door. Receiving no answer, Rose placed her ear against the door and upon hearing the laboured breathing on the other side took in a sharp breath of her own. She knew whatever was going on in there was not something Cerys would want the Doctor knowing about.

"Are you all right, Cerys?" It was a stupid question to ask, on that if her friend were beside her would give her the famous 'are you shitting me' look. Still, it was a question Rose needed to ask, even if it was mainly for her own benefit. She reached for the knob and jiggled it a bit, finding that it was locked. "Let me in." When the door remained unlocked, the blonde glanced over at the Doctor who had been watching the entire thing curiously. "Please, can you open it?"

From how Rose worried for the other girl, he knew something was wrong with her. He would have asked but they had only been with each other for two adventures and he was unsure if either girl would share information on Cerys' ailment. Making a decision though, he pulled out his sonic screwdriver and sonicked the door. Once the lock clicked, Rose all but pushed him aside and rushed in. The moment they were inside, they found Cerys passed out on the linoleum floor, breaths shallow and upon further inspection, heart rate slowing.

Rose had to think of the last time Cerys took her medication and figured it was back before they began travelling with the Doctor. She muttered a few choice words at her friend's irresponsibility. Cerys should know better. After the last time, she knew to always have them on her. Running a hand through her locks, Rose turned to the Doctor, put off by his silence. Instead of yelling at him, she decided to ask for his assistance instead. "Can you held me turn her over. She shouldn't be on her stomach." Without a word, he helped turn the brunette over.

"I'm going to get the Tardis. Park it in the back. Think you can manage getting her out there?" Rose cocked a disbelieving eyebrow at him before waving him off. She couldn't be bothered by him at the moment, especially with the fact that without the proper help, Cerys could fall into a coma and die. She didn't want to think of that possibility though.

Against her better judgement, Rose managed to get Cerys in a sitting positon and after much struggle, onto her feet. She almost collapsed under the dead weight as she tried to find her centre. As she began to leave the room though, the Doctor showed up. Turned out they were taking way too long for his liking. Ignoring Rose's struggle, he swept his arm under Cerys' legs and hefted her into his arms. Rose stumbled by how quickly he had done so but once she regained her balance, she followed him to the Tardis.

Once inside, she followed him as he brought Cerys to her room and laid her onto the bed. Grabbing the quilt at the bottom of the mattress, Rose laid it over her friend and walked out of the room. Much to her surprise, the Doctor remained inside for a while longer. Rose wasn't sure what he was doing, but she hoped he wasn't doing anything to bad, not that she thought he would. Knowing they would have to discuss what had happened, she decided to wait for him in the console room. It made sense; it seemed to be the central meeting area on the ship and she knew he'd end up there eventually.

The Doctor didn't disappoint. About five minutes later, he stalked into the console room, deep in thought. There wasn't much he was able to get from Cerys while respecting the fact that it was something she didn't want shared so he was at a loss on how to treat her. It was quite infuriating, especially since he had an inkling as to who she really was. Consumed by his thoughts, he didn't register Rose's presence until he almost bumped into her. "What are you doing here?" It came out harsher than he intended and it was evident in how the blonde's eyes narrowed at him.

"I figured you would want to talk about what happened."

"And are you going to tell me?"

Rose grit her teeth. "Not if you continue on like that."

The Doctor sighed, knowing he was being a prat. He was usually quite good at keeping up the impression that he wasn't that bad in terms of his companions. But with what was going on with Cerys, he couldn't help it. He felt just as helpless as he did with- NO! He couldn't think of her. That was a luxury he couldn't allow himself after what he'd done. Instead, he brought his attention back to the blonde. "Sorry. Go on then."

"This hasn't happened in a while. The last time was a year and a half ago." The Doctor nodded. That was fine but he wanted to know what caused it. He wanted to help her. "I don't know why it happens but I'm sure Cerys does. She won't tell me or mum though."

Perfect, a person who doesn't want others to know why a certain thing happens to her. People like that made jobs difficult for medical practitioners. "Is she ill?"

"Will it keep her from travelling?" Rose questioned. She didn't want to answer that question unless she knew the Doctor would let her stay. She didn't want to be the reason her best friend had to go home, not that she would stay if that were the case. Rose just wanted to make sure the Doctor wouldn't mind having someone in Cerys' condition travelling with him. "Will you bring her home?"

The Doctor shook his head. He would never send Cerys home because of that, he wanted her around more than he actually wanted to admit. There was just something about her that intrigued him greatly and the fact that she made those delicious pastries meant that the longer she was around, the more he'd get them. "I just want to help her. I don't think I'd be able to just leave her."

Rose stared at him in disbelief. She couldn't believe he'd said that. To be honest, she thought he'd actually say that he didn't want her around. It wasn't something she knew he'd say, but it was something that kind of made sense. In most cases, Cerys was looked at as a liability. She was too reckless at times and her medical issues flared at the worst times. Her best friend was a walking medical disaster waiting to happen and the face that she wasn't looking after herself properly made things so much worse. "Wait, what?"

"I just want to know what's wrong so that I can help. I do have some medical knowledge."

"So she wouldn't have to leave?"

"Nope."

"That's good." Rose smiled at him, happy that they would still be able to travel with the alien. She knew her friend was growing attached to him, and she glad that it was happening. Cerys often had a difficult time with other people and it was nice to know that she had found something in the Doctor that was worth getting to know. But she couldn't help but think that the Doctor was also very much interested in her friend. His comment was enough to prove that thought. He didn't want her to go. Maybe, just maybe things would work out wonderfully between the two. "You know, I think you like Cerys."

"Of course I like Cerys. I wouldn't have her here if I didn't."

"No, but you care about her."

"I care about all of my companions, Rose." The Doctor's brows were furrowed as she tried to understand what Rose was getting to. She was being confusing. Of course he liked and cared about Cerys. He felt that way about all of the people who travelled with him.

"I think you care about her more than you do the normal companion." Rose smirked victoriously when she saw the reaction the Doctor gave at her words. She knew it was true. While he wasn't much help with Jabe, he seemed to calm when Cerys was around; he listened to her when she spoke.

The Doctor's ears grew red when he finally realised what she was trying to say. There was no way she was right. If anything, Cerys reminded him of someone he held dear. Like a typical human though, Rose was jumping to conclusions. It was a bit irritating but he didn't know why he found it so. If her words were false it shouldn't bother him, right? "You are wrong."

"No, I'm not." Before the Doctor could retort, the two saw Cerys enter the room. Knowing that their conversation wasn't appropriate for her ears, especially since it was about her and the Doctor having a semblance of feelings for her the two abruptly ended their conversation.

The Doctor on the other hand was happy for her interruption. It took Rose's focus off of him, something he found he disliked when she was trying to make a point to him. He knew she was wrong about him feeling something for Cerys that was outside the realm of a companion. He didn't feel that way about anyone, not since HER. No, Rose was wrong and Cerys was just a companion. Yet, why did he feel as if he were lying to himself?
