I think Alex was a grad student that Sheldon hired and there has been no mention of her returning next season. After all, grad students graduate and move on. Maybe she will be around for another year, maybe not. What would be REALLY fun is to see Ramona Nowitzki (not sure if I spelled that right) from Season 2 return - she could have obtained her own Ph.D by this time and still be trying to hitch her star to Sheldon's wagon! Especially as it appears Sheldon is going to have a major breakthru this season!
