Puppy Love
"What's your story, then?" Sam kept his gaze on the Doctor and Dean as they bartered with a merchant for car parts. All of time and space, and Dean still cared about fixing up his precious Impala-probably guilt he felt for leaving her behind so often since meeting the Doctor. Sam opened his mouth to give an immediate answer-an immediate lie-when he realized he didn't have one.
He glanced down at the woman beside him then did a double-take to make sure he wasn't just seeing things. When first meeting Donna Noble, Sam had pegged her as one of those hopeless, loud, wild cards you try to avoid while at a social event. She'd been on her best behavior while traveling in the TARDIS. But if the coy smile was anything to go by, now that they were alone all bets were off.
Sam gulped audibly.
