Well if you can bare to read RTDs interview on AfterElton, it appears that they got it pretty spot on. They mention a Rex Matheson and someone called Esther so who know what else digitalspy got right?

Okay have no idea if I'm doing this right, but anyway. I've just read in the Torchwood Magazine that they'e just put a casting call out for 4 new characters. Rex Matheson, Esther ..., Dr Vera ... and another guy. Rex is late 20's CIA agent. Esther is early 20's CIA analyst.
Can't really give you much more than this, as didn't buy the magazine, just browsed it in WHSmith's. Hope this is ok.
