Path Pt I: (Interesting thought)

The shoes that Emilin wore were exactly the ones that she had previously mentioned while texting her big brother Theo, the ones that he had gifted her before he went off to college and she to her travels.

The thin needle that she held had a special magnetism. 

In order to activate the special mechanisms in the shoes, the needle had to be both close enough to the corresponding hole in her shoes as well as long enough to reach the bottom of the high heel soles. A click sound could be heard when the mechanism was successfully activated.

It was able to change the signal that was being sent to her big brother Theo's computer, which her big brother Nathan would also be able to access in the case of an emergency. 

The shoes were built-in with a GPS that worked even with poor signal or no signal at all.
