The number one thing Jack Harkness never wanted to hear about or find over here in the states were Daleks. However, as was always the case with Jack Harkness and that annoyingly stupid thing called 'luck' was that it always seemed to not do what he wanted it to. Which was why Jack was grumbling and in a less than pleased mood: there were Daleks.
Joy, rapture, and all that jazz.
Jack wasn't sure what was being done about the Daleks, hell -- he was too far out of the loop on far too many things. Christ. Which was why Jack was out to see what could be done. While part of him knew there was nothing to be scared of any longer -- Jack still inherently feared the Daleks and probably always will. Webley loaded, he headed out to see what he could see.
