((Her name is Erin, after going back in time to get out of a failed dystopia, she went back over 20,000 years, you met her a few months ago, and decided to let her stay with you for the time being))

you and Erin were walking to school when she reaches into her pocket and pulls out a small, pink, floating cube, inspecting it somehow

Erin: ugh.... Still no connection... Dammit
