Mark twitched her nose and as the mouse side of her brain attempted to take over, screaming that this area was too exposed and they she should head for cover, Mark refused to listen as she simply told herself, "I refuse to be some rodent! I will not be a female!" and began making her way toward the vials.
The first problem she found as she approached the vials was her size, about three point nine inches long, compared to the size of the vials. But the she remembered that size did not really matter, seeing as normal mice got into stuff that was much larger and moving over to the vial, Mark began to crawl amongst them.
Her next problem came with a start when she realised that she could not read or understand what was written or printed on the bottles and wanting to cry, Mark cursed her rodent brain as it took over another bit of her human self.
Settling on the fact that she would just have to try a vial and hope for the best, Mark shifted about, but quickly came to the conclusion that she would not be able to extract any of the contents without her human hands. And then she remembered her teeth and shifting about some more, she began to work slowly on the lid of one of the vials, hating the way the plastic tasted in her mouse, scared that sooner or later somebody might come in.
Moments later, Mark lets out a squeak of victory as she punctures through the top. But her victory is short lived as the part she is sitting on gives way and she tumbles into the vial, becoming lodging partway and ingesting a fair bit of the fluid into her nose and mouth.
And then she feels the familiar sensation as she starts to transform.
