i didnt watch the last 2 episodes either. but i asked a friend who did watch it adn she said that Chris did die, and Piper was pregnant so she also gave birth to chris in the present. cant give you details on how he died so you might wanna find a site with (old) spoilers!
thanks! id did watch the last two episodes, but all i remember that chris went through a portl back to his own time... so weird, i'm definetely going to look it up somewhere.
I watched every episode and i can tell you that he was stabbed by Gideon and when he died he disappeared and that is when Piper gave birth to baby Chris!
