Mason Starkey (brother);
Jenna Starkey is the adoptive sister of Mason Starkey—the biological daughter of the parents who took him in. The night before Christmas, Jenna had been sleeping when the Juvey-cops came for Mason, whom their parents were sending off to be unwound. Awakened by the commotion, Jenna was livid at them for wanting to unwind him because he was storked and made a case, telling them that they might have had her unwound too if she was storked. When her father told her to get back to bed, she defiantly refused and witnessed Mason's departure.
