You never know, I would hate to have a nasty mid-season surprise.

i think that new shows start bad but then they come out good i mean look at lost they been on forever and despeate housewives nathan was on that so despeate housewives fans might watch castle now

i dont watch DH because its kinda annyoing like all they do is gossip and fight and have affaris thats bassicaly it and my parents said i could not watch it so i cant even if i wanted too

Davidsmom, when you're on your main twitter page, you should see a 'bar' at the top right hand corner that says "Home | Profile | Find People" etc. Click on "Find People", then type in Nathan Fillion into the search bar that comes up. You should then see his profile icon (currently him in costume in front of a green screen), as well as his username (NathanFillion) and the number of followers etc he has. Click on the username (in blue) and it will take you to his main twitter page. Under his icon/picture you should see a box that says 'follow', click that, and you'll see updates on your page every time he tweets something new. All of his posts (or 'tweets') are listed on that main page of his, so if you want to read back you can see them all in chronological order. I hope that helps you out, feel free to ask more questions should anything be unclear :)

By the way, what's your twitter username, there are quite a few of us Castle fans on there so it would be nice to 'follow' you as well :)
