1x01 Pilot
Look like they reworked this episode from what i saw above with the only difference is that took out mystery behind Dash brother and introduced him in the first episode not sure if that's a good thing or not due to the fact it was suppose double role for actor who played Dash which suggest there didn't have enough confidence in him to do that .
Overall even with the rework my opinion is still same i am pleased they changed clifhanger from first episode .
