Sam chuckled, "Didn't Zachariah say something about you having daddy issues?"
Dean glared at Sam, but he continued to laugh even though he tried to compose himself.
"What the hell are you talking about?" Dean demanded in a husky tone.
Caithrine rolled her eyes, "Do want me to spell it out for you? Draw you a picture maybe? It's not that hard to understand," She snapped, snarky, "Your name was on my birth certificate. My mom died. Now you have complete sole custody of me."
Dean blinked. Was he going to believe this girl, or continue to try to disprove her? He was just starting to trust Sam again, how could he trust some random girl who walked into his room unannounced and claimed to be his daughter?
"But suddenly he wanted to believe, as he so longed to with Ben back in Cicero, Indiana.
"What do you want? A blood test or something?" She snapped.
Dean tried to sound harsh but unexpectedly, his throat was tight. "Yeah," He snapped back weakly.
The girl sighed in exasperation. She turned to the bed and harshly grabbed a bag Dean'd never realized she had. She grabbed a small CD case out of her bag and tossed it at Sam, "Install this on your computer." He looked with bewilderment from the case to Dean, then reached for his bag by the other nightstand. "And toss me that." Caithrine pointed to a small silver blade on Sam's bedside table. He picked it up slowly until she nodded, then he tossed it at her. He was afraid for a second hat she would miss and hurt herself, before she caught it perfectly by the handle.
Dean watched intently as she set it down and reached into her bag. She pulled out a small black card and set it on the bed. She picked the blade up and cut herself on her left forearm. Dean ground his teeth; silver ruled out a lot of things. Caithrine took a small clear shield off of the black card and lay it over the cut gently, then peeled it away like the backing of a temporary tattoo, and lay it, bloody side up, on the black sheet of plastic.
Caithrine took a Kleenex from a box on the nightstand and wiped the blade clean. She pulled out another black card. She flipped the knife around in her hand so the handle was facing towards Dean, "Your turn," She said.
He hesitated a second the swept the knife from her hand aggressively. He quickly slit his upper forearm, and set the blade aside. He repeated Caithrine's steps as he had seen them with the card.
"What is this?" Sam asked.
"An at home blood test program," Caithrine said in a tone that implied that he was an idiot for asking.
"Where do you get something like this?"
"My mom worked at a hospital, they were running some crash tests with it. I managed to snag a copy."
Sam gave her an incredulous look which she gracefully ignored. Sam shook his head a little, "Um it's installed."
"Perfect." She pulled another black card out of her bag and place hers on one side of it. She put her hand out for Dean's without looking at him. For a second he considered slapping it blood-side-down in her palm to see how much she would freak out, but decided he rather get this over with faster and just set it down in her hand. Caithrine lay it down next to her own on the larger black card then picked up the whole unit. "Put this in you floppy disk drive, then click read."
"Floppy disk drive?" Sam asked, trying not to laugh.
"Don't tell me you don't have one."
"No I do its just – who uses those anymore?" Sam chuckled.
"We're talking about the hospital, they never update."
Sam attempted to sober up and nodded. He took the card and slid it into the drive, trying carefully not to egt any blood on his precious laptop. The he clicked read.
A small box popped up on the screen:
Estimated read time: 3 hours 47 minutes
Dean saw the screen and demanded, "What the hell are we suppose to do for four hours?"
"Ooh, lets go to lunch," Caithrine said with mock enthusiasm.
Dean glared at her, but she continued to smile perkily.
