So he sets a clever little trap for probably-his-girlfriend, after he notices someone following them and probably-she knocks him out, and he turns out to be totally right: it's his girlfriend.

Tally still won't look at him, but he can tell that she's reprogramming herself.  Being in the wild is making it go faster, he thinks.  He says so.  She still won't look at him.

The thing that started all this was a kiss...

She's the one who closes the last bit of distance.  And honestly, she seems pretty into it, into him, like their days back in New Pretty Town, quiet, always talking around what they meant so as not to trip the minders - her hands reach under his shirt, pressing into him, pulling him closer; her arms, so much stronger than his and not quite gentle enough, compress the air out of his lungs - he puts a hand to her cheek to let her know he doesn't mind, that it's all okay, and it is -

For a moment.

He feels her freeze up.  He tries to hold her closer, to reassure her, and then there's a flash of pain across his hands and he's not doing that anymore - now she's over there and she falls to one knee, breathing hard.  She looks like she's trying not to throw up.  (Ouch.)  He asks whether she's okay, even though she's obviously not; she confirms it.  "I just can't, Zane - " and she jumps off the cliff and into the ocean, almost too fast for him to see.
