Look at Crysta's reaction to Zack when they exit the cave when he's still holding her hand all attached now.
That is the face of a girl who just fucked a guy she met not long ago, he's now getting clingy, and she's like "Oh man girl, what have you done?" I'm not saying she's not attracted to him. But she let things go too fast, she didn't fully consider the consequences (lucky for him, it was only gaining fairy touch power to feel forest's pain) and she doesn't even know him that well (he proves this soon after).
She even gives him a cold shower when he's pulling her in for seconds.
Zack and her look to be around college age which is when hormones balanced with maturity where risking fucking happens most.
Works as an interesting allegory for how humans fuck nature. When Crysta finds out who he really is, she feels used and manipulated. It's why stopping Hexus isn't enough to make up for what Zack's done. To fully amend, he must leave her (no more fucking nature and the fairy).
