Pam's fangs drop, and she bites her own tongue.

Cradling the back of Jemma's head, she leans down and kisses her, her tongue slipping between her slackened lips, giving her a taste of her blood to help revive her.

Then, as she pulls back, she tsks. Jemma's shirt collar is stained with blood. Eric is such a sloppy eater.

"You need to replace this," she tells him as she unbuttons her collar.

Leaning down again, she licks her wounds closed, making sure that the fang marks heal over.
