Last issue Jean was only in like 3 pages, but that was because the entire issue was instead focused on her sister Sarah, revealing what happened to her following her last appearance in X-Factor and how she died. However, she knows has no idea how she came back from the dead nor how she got to the planet Elarunn-7 and created Greyhaven. Cable on the other hand does, but he seems to know much more about her as he immediately blasted her once he arrived!
