I glance up at Cassandra across the table, and find that she's completely and utterly still.

That's the first red flag. Because, in perfect harmony with her ceaseless energy and witty personality, Cassanda Olyen is never still. It's like she's in perpetual motion; always with a knee bouncing, hands fidgeting, mouth chewing. Even as she sleeps she moves, always tossing and turning and squirming.

But now, amidst the chaos of this warm meal, she's motionless. And it sets my heart pounding.

I tap her shin with the toe of my boot, and she glances up at me. Her face is sort of grey, her eyes unfocused and her mouth tightly shut.

"Cas? You good?" I prompt, but she just stares at me. Then, just as I'm about to get up and suggest we take a moment outside, she shakes her head very, very slowly.

"What's the matter?" Simon asks softly, her quiet voice trapping us in our own little bubble within the bustle and clamour of the others.

Cassandra opens her mouth slightly, as if to speak, before it snaps shut again and she bolts up from her chair and out of the room without a second thought. I share an alarmed glance with Simon, who immediately has Juno by the hand and is standing to announce to our hosts, "Thank you for dinner, it was amazing. But I think this little one ought to be off to bed now, so we'll be disappearing for the night!"

The man who lead us here earlier- Tom, I think his name is- nods curtly. "You've been good company. If you don't know where your rooms-"

"We've got this, thank you! Have a nice evening!"

And on that final note, Simon has me by the elbow and is leading both Juno and I out into the corridor. Cassandra isn't anywhere in sight, and I breathe in a deep sigh. With the sheer size of this camp, we could be searching for hours.

"We'll check our rooms first," I decide, and Simon seems to agree. "We stay together like usual, yeah? This is a new place and I'm not sure.."

"Together." Simon concludes, cutting me off as we begin down the path we came from earlier.
