Gideon has multiple means to increase her speed, so if she can have fun while in transit, that's what she'll do. Flying's more fun with someone than on her own. At least at her skill level for flying.

"Ah, but you didn't up and disappear," Gideon says, "Think of it like pressing pause. Stepping out while the rest of the world doesn't move. No one will know. No one will care. It's free time, baby."
