I found the episodes via sidereel but was directed to the best copies of those episodes on megavideo. Megavideo seems to be replaying those episodes shown on CTV. I will post links I used for episodes 9, 10, 12, and 13 but for ep.11 there is currently no megavideo so I found another poor quality link on sidereel. Keep in mind on sidereel there are several ones listed so you will have to sift through and find one that is watchable.
Episode 09 = http://www.megavideo.com/?v=39FKKP7R
Episode 10 = http://www.megavideo.com/?v=3WCCWYMN
Episode 12 = http://www.megavideo.com/?v=38F65VHK
Episode 13 = http://www.megavideo.com/?v=SHSTZOJL
I loved this show! It's not totally on par with LOST ,but has many similar elements and I believe the show was really starting to hit it's stride by episode 13. I am very disappointed it will not be continued beyond the "Kiss Gravity" episode. Maybe just maybe, if ABC does ever air the final episodes 9-13 and if viewers make enough commotion, more episodes will be made. I realize this is pure pipedream, but hell...ABC takes off half a year to make the final season of LOST, so they should go back and make more Defying Gravity!!!
