Bobby refused to say why it was their kind of case when Dean asked, knowing that'd take only a few moments for him to look over Mika's shoulder at the paperwork for him to work out exactly why it was their sort of case. Which was proven as Dean said exactly that it was their case as he did see more of the case information. He smirked as Deanc omplained about the long drive to Minnesota, just as he planned he thought to himself. "Quit yer whining ya idjit. Thought it'd be good for you both to do it but if you don't wanna take it...." he replied, trailing off his sentence before he said 'I'll give it to someone else'. 

Mika also didn't like the fact it was such a long drive, but judging by the devious smirk on Bobby's face as she glanced up,, he knew exactly what he was doing. "You just want us out of the house for as long as possible...don't you?" she accused him, but her tone was also playful. "I don't know waht you're implying" Bobby said sarcastically. "It's not like you're short of cars to take i'll even let you choose between your car or another one that's good to go and not a customer's" he reasoned with a shrug. 

"Consider it bonding time with each other and a real test of your relationship. you survive this drive and back I'll buy you a new bed" he bribed his niece. "Oh you drive a hard bargain dearest uncle of mine" SHe smirked but narrowed her eyes at him, as she shoved in the last mouthful of her breakfast to her mouth. She then looked at Dean, "whaddya say?" she asked him.
