Spoilers for Miracle Day

Esther didn t even know why she felt that way. She had no idea, why, when Gwen threw her arms around Jack s neck she felt nothing but a sharp pang of jealousy. She couldn t put her finger on it. Why should Gwen just take him over like that? Had Gwen had to drain ounces of Jack s blood, every, single day? No. Had Gwen been watching Jack night and day, to make sure he didn t lapse back into unconsciousness? No. Had Gwen driven for miles, and miles, and miles with Jack bleeding out into the rugs of a stolen car? No. So yeah. Esther figured she d bonded with Jack. The only mortal man. That s why she got jealous. Gwen had bonded first. All Esther had was that initial spark of attraction. A one sided attraction.
