Mika knew she had must have injured her leg when she quite literally fell through the cavern ceiling earlier, but she never realised it was quite as bad it was. A fully blown open gash wound a good eight inches down her calf. Not only that she was partially certain that she had done some kind of damage to her ankle as she fel at such a bad angle, there was no way she would be able to drive back to Souix Falls tonight, not in this state and from the way Dean got beat by the ghost, it was clear to her that he wouldn't be able to focus on driving either. 

When he skidded down to her level and finally saw her leg injury, she just gave him a shrug "I think I fucked up..." she winced with a half snigger, as she tried not to let the pain finally get through to her. "I'm not sure..I'm hoping some exit at the other end there" she replied, nudging her head to in front of her. "I didn't really get a chance to spot an exit after I fell through the bloody ceiling" she told him hissing and hitching her shoulders up as he pressed his tshirt against her leg. She nodded and did as he told her to, pressing his shirt firmly against her leg. 

"Try straight forward...there has to be another way out of here that's not however you got in here" she told him, trying to hold onto his shirt on her leg with one hand, and onto him with the other as she knew if she had to walk, she would slow them both down even more. "We gotta get our stuff though" she reminded him, knowing at least her bag was still laying around. She didn't say anything but truth was, she was actually scared for the first time in a long time on this case. She was convinced she was going to lose Dean until she managed to kill the spirit just in time. Her leg hurt so damn much and by this point, tears from the pain did infact start to fall down her cheeks as she leaned into him more.
