The moment Dean threatened Sam with shooting him in the knee if he ever so much as tried running away again, Mika knew he wouldn't really do it. He loved his baby brother far too much to do actual bodily harm to him and knew he would be quicker to hurting anyone else who hrut him and see to Sam's wounds than cause harm himself. Yet the similarities between this Anna girl and Dean with not wanting to be alone didn't go amiss on Mika. She knew a lot of the time that Dean asked her to share his motel room with him or asked her if he could crash in hers, was simply down to him not wanting to be alone. If she truly honest with herself, that was one of her reasons for always accepting and agreeing to be with him in their messed up way. 

Sam was ready to say something back to Dean, but Anna stopped him by pulling his head to her and reassured him she would be okay. He didn't believe her and wanted to help her get freedom from her mother, but he didn't know how. SO all he could do was nod and let her brush his hair behind his ear yet again. Closing his eyes briefly, he let the kiss linger on his lips before reopening his eyes and watched as she grabbed her bag and made a swift exit from the building, running out into the woods where it wasn't safe. 

"Nothing was going to stop her running Dean, you and I both know it. She seems like a tough kid, we can only hope she'll make it" she told him, really hoping that the vampires in town wouldn't find her and rip her apart on principle or kill her for food. She then turned back to Sam, "Come on, lets get back to the motel" she suggested, going to put her hand on his shoulder but he just shrugged her off of him and starting to head to the door. "Well? We going or what?" Sam asked them both, "And if dad doesn't notice us all coming back, I won't tell him you got her here after everything he said in the car" he told Dean.
