Aw, man. I didn't realize the show was now airing on Wednesdays... so I missed ep 2 (which will be available to view several days from now on the ABC website).

Just got through watching 7X01. I like this take on time travel. That you can cause a ripple, but just don't create a wave... I can foresee several moments of "Oh, crap is this action going to cause a wave?! "
