Cassandra clearly thinks Gideon's lying, which she's right about, but how dare she anyway. If she wants to tenderly hold Gideon's hand, she can do it because she thinks Gideon's muscles are worth swooning over, because Gideon has had enough of people making her sit down and learn things she would really rather not. Save her for endless lectures about the world.

Thankfully, Cassandra's polite skepticism has given Gideon all she needs to bolster her lie. "Sure is. But since I did go there and get told everything, I can go anywhere I want around here."

And proof of that, Gideon simply picks a direction and walks in it, turning around halfway through to spread her arms in a told-you-so shrug. Why didn't Gideon get an orientation? Who knows, who cares, she's not looking a gift horse in the mouth.
