As noted previously in the notes under the bio for Manifold, Jaymie, is her half-sister. They have the same mother, but different fathers. Both men didn't stay in their lives for very long, and eventually their mother didn't either. Sara, being ever the optimist just rolled with it, and made the best of her life, but Jaymie took things a little too hard, and got into a life of troublemaking and illicit activities, which soon drove a wedge between them until they found each other again and Jaymie was brought back into the light. Well, she may have left her life of crime behind, but she does still hold onto her darkness somewhat, as she still wears her costume from her time under the control of the S.P.I.D.E.R.W.E.B. terrorist organization as a reminder to herself to never allow herself to go back to that lifestyle, and also as a way of mocking her former captors. And, now with the power of the "Manpower Chip" in her head giving her the ability to capture and control others with a set of energy webs that she can conjure, she has taken the name "Manipulation," which perfectly fits her attitude of being the one in control and not liking to be controlled. This makes her somewhat of a wild card on the team, but as stated above, as more than just a team, but a family who are together to fully support each other, not harm each other, there is little to no fear of her going rogue again, nor the need for her to use her powers against her or she using hers against them. For, she fully intends to only use her powers against villainous scumbags who truly deserve it.
