You had Adhd, It wasn't normally a huge problem as you had your meds and the team was aware of it. Though, your Captain did notice how you'd always fiddle with things in your hand during downtime.

So, Price bought you what was called a "infinity cube." He didn't know much about it but it did make him smile as he saw you mindlessly playing with it in the common room.
