For those of you who, for whatever reason, missed the show, here's where you can view it at NBCs Video Rewind:

Heroes KINDRED episode 3 on NBC TVs Video Rewind
(opens in new window)

For those who cannot view through the NBC site, try TV-Links (UK)

Heroes KINDRED episode 3 on TV-Links (UK)
(opens in new window)

I just linked the TV-Links mainpage this time, so find "Shows" and "H" and Heroes episodes will be there.

Enjoy!
