Not sure how; I try to be vigilant about when shows I like return. I did not even know they did a 5th season, somehow thinking they were done after 4. The same sort of thing happened to me in season 4, so it's my own fault (I missed the first few eps there, got them later). Of course that time they pulled a head fake and moved from CBS to ION (whatever that is). But at least they are showing repeats (I jumped in about halfway into those). It probably has a lot to do with the fact that I would probably never watch ION if it were not for that show, and that ION does not cross-promote to cable channels, or anywhere else; if you are not watching, you have no idea what's on that channel. Stupid ION. To me, the fifth season wasn't even a rumor. So they had a 5th season; who knew? And of course ION on DTV hasn't really been HD all that long, from what I can tell, so I was in the habit of avoiding it for that reason as well. But its a pretty wonderful world where your biggest TV problem is its hard to keep track of all the good shows on so many different channels, I guess. I have started a new Flashpoint drinking game where you take a shot every time that guy yells "Right there, right there!".
