Sheldon woke early about 6.30am, he got up and went into the tiny shower room, he switched on the shower and got underneath it.

The noise of the shower woke Penny up, she opened the curtains to look outside to see a sunny morning. She had slept very well considering she was on a train that stopped at several stations throughout the night. She sat up and tried to brush away some of the sleep from her eyes.

Then all of a sudden she started to have thoughts she never expected, all she could think about is that Sheldon was naked under that shower. When did she start thinking about Sheldon like that? She blushed. The shower stopped and she could hear Sheldon moving about in the shower room.

Her thoughts turned to the conversation they had just before she turned off the light and fell asleep last night. Sheldon didn't really answer that question. So do you assume that yes he had been in love? Penny wondered who he would have fallen in love with, and if they ever knew? The door to the shower room opened and Sheldon stepped out in his bathrobe. His hair was still wet and tousled and Penny thought that he should always wear his hair that way, she also wondered if she could tempt him to wear it that way on Saturday night at the reunion.

"Good morning Penny."

"Morning Sweetie, it's lovely day."

"Yes, mmm." He wasn't good at small talk. "The shower room is all yours, I have cleaned the shower alcove for you and sanitised the toilet."

"Oh, you shouldn't have." Penny grabbed her bathroom and started the climb down the ladder, except she slipped.

Sheldon grabbed her and stopped her fall. His arms wrapped around her waist, and she grabbed at his forearms to steady herself. She looked into his eyes, his strong blue eyes, then she blushed for the second time that morning.

"Thank you Sheldon, nearly came a cropper there." Penny quickly grabbed her toiletries and shut herself in the shower room. She could still feel his arms holding her, and his forearms were toned, not scrawny liked she assumed they would be. Holy crap on a cracker, what was wrong with her this morning? She can't be having thoughts like this about Sheldon.

Penny showered and dressed and they went to have breakfast. It was eaten quietly, neither really had much to say.

Sheldon broke the silence "Did you know that James Watt did not invent the steam engine as is commonly believed?"

Penny looked up from her food, "No Sheldon I didn't."

"A man named Heron did, he was an Egyptian living in Alexandria about AD62. His invention the aeolopile or "wind-ball" was the first working steam engine. Using the same principles as jet propulsion a steam driven metal sphere spun around at about 1,500 rpm. Sadly it was seen as just a novelty, no-one understood it's practical uses."

"Oh." Penny looked up at Sheldon. She was thinking that his eyes were intensely blue this morning. "Good to know."

"If only Heron knew that the railway had already been invented some 700 years beforehand and the two inventions had been combined we would all probably know his name today."

Penny looked at Sheldon, he was twitching and blinking like he did when he something was bothering him, perhaps he was still trying to come to terms with actually having touched her this morning, whatever it was going on in his head he was not comfortable. He stood up and announced that he had some work to do and would be returning to the compartment.

Penny decided to stay and have another coffee, and let Sheldon calm down, and give her some space from him. She couldn't believe the thoughts she had been thinking about her ex boyfriends room mate, a man that she knows first hand is as Leonard says, "one lab accident away from a super villain". The man that hung her panties out to dry so to speak, Dr Wack-A Doodle himself. Get a grip Penny.

The rest of the day Sheldon seemed determined to work and didn't talk very much, and Penny was happy to continue to keep her distance from him. After they returned from dinner, which was eaten for the most part silently, he was still looking uncomfortable and Penny decided she needed to ask him what was wrong?

"Sheldon, you've been uncomfortable all day sweetie. What's wrong?"

He was packing her bag, as tomorrow morning they would be departing from the train. He turned to look at her. "Nothing's wrong Penny."

"Sheldon, you've been twitching all day that means something is wrong with you. Was it because you grabbed me this morning?"

"Don't be silly Penny, I'm fine there is nothing wrong with me." he twitched even whilst he was talking to Penny, he was a terrible liar.

Penny shrugged her shoulders, "Ok, if you say so Sheldon, but I don't believe you."

"Penny we should turn in, we have to be up at 4.00am tomorrow morning." Sheldon went into the shower room to brush his teeth.
