Allison Johnson had low-level precognition, which usually presented as a feeling about an event in the near future. Before she died, she’d felt a terrible dread all day.
Grace Johnson can cause confusion/disorientation in people through touch. However, it immediately ceases when she’s not touching them.
Tobias Johnson could cancel out the powers of anyone nearby, up to about ten feet.
Jill’s relationship with her mother improved after the penultimate chapter of Mercury, and by the time of the epilogue they were friends. Jill worked very hard to make sure her mother was given a good home, education, vocational training, and appropriate post-cult mentoring. Grace was approached several times by journalists who wanted to interview Jillian St. James’s daughters (Marco’s mom was approached, too), but only after years of recovery was Grace comfortable speaking about her mother. Grace found a great deal of solace in her new career as a hair stylist, where she can spend the day with other women and make people beautiful. She now works in one of Gabriela’s salons.
Jill’s relationship with Mason is complicated. Mason bears the same emotional scars from an abusive father that Jill does, and it’s hurt his ability to bond with his siblings. After the camps closed, he struggled to find his place and identity. His fiancee, Justine, ended things with him, wounding him further. It was Reuben who reached out to him (after Jill confessed her troubles to him) and offered him a job as a handyman around the Fischer’s enormous home. Spending time with the Fischers, seeing how they treated each other with love, and getting time to reflect on the future softened Mason a lot, and by the time of the epilogue, he’s working for a handyman company and dating a lovely young woman. He calls Jill occasionally, and while they’ll never be best friends, they’re both happy with how things are.
