Does the Team Xen naming scheme have any importance outside of WLL because I'm pretty sure that Madelis' 'Lis' comes from her sister Lisbeth and Geara's G(i think) from the name he used in the past (Gregory I believe).
Also Melanie mentioned that probably Madame X does not know that merging with the other self in an alternate timeline does not delete them and given that she has a Time Diamond and she has used it quite a bit, it could mean that she has a few alternate versions of herself inside her somewhere,
