The four pilots split up the moment they arrived on Helios. It wasn’t as though they didn’t enjoy each other’s company (well, for the most part anyway). Simply, they had spent a couple hundred hours with each other, in that lab. They were sick of the project, of brother and sister Chase, and of each other as well.
They seriously needed a break from all of it.
So they bid a temporary farewell to each other, then headed on their separate ways.
Redstar went off to find her racer and jock buddies while Merlin spent some time with his crew. Miko decided to visit a hackerspace and get her coding game on.
Eva decided that she needed to sweat a whole lot. Though she had worked her mind to death the past two weeks, her body had languished to some degree. Being the kind of person who needed to keep moving, she associated sitting in a core for hours to plain torture.
