Help...I'm new to the series and I can't understand something.
It might be silly... but when I was watching part of the show online the episode said doctor who. I later figured out that doctor who is a spin off. I wanted to get torchwood but do I I have to get doctor who too? I think it was the episode when Jack came back 또는 left 또는 both. I forgot now but it was an important part of the story I was watching at the time. Sorry I know it sounds like a really stupid question. Props will be given to anyone who can give me this info.
