[Dan kind of stands around awkwardly as the teaser plays. Eagle-eyed fans might notice him mouthing the words.]

[Soft-focus shot of a park on a sunny day, Julien on a bench with legs crossed, texting rapidly. There he is on voiceover.]

We can't stay who we were forever.

[A bunch of images and brief clips play as the voiceover continues. Hanging out with various other characters, X-ray type images of his lungs and voicebox, a closeup shot of his horizontal blink, working in the clinic. The voice effect starts subtle and gets progressively less so.]

Even if you find a way to stand still, everything else will leave you behind. No matter how hard you try to prevent change, it will still come. The world, and your friends, will still change.

[Back to the bench, a closer shot. Julien's still texting, but looks worried even as the voiceover becomes passionate.]

Of course it scares me. What's waiting on the other side? No way of knowing until we get there. So! Keep your chin up. We'll make it if we keep going - whatever happens, don't stop. Always move forwards!

[Cut to black, and the last line is delivered in a tired, cracked tone.]

Right up until you can't.
