If you watched Syfy‘s Helix live last Friday night for its two-episode premiere, or at any time for its 24 hours of replay on Syfy last Saturday, and if you didn’t speed past every single commercial if you watched it on DVR, you know that Episode 3 has been available On Demand and on Syfy.com since Friday night. If you did miss the third episode, don’t worry; the broadcast premiere is tomorrow night, Friday, January 17 at 10/9c.

If you didn’t watch the premiere last weekend, I expect to see a doctor’s note on my desk in the morning. Seriously, don’t miss the chance to watch this “very serialized” series from the beginning; Syfy is replaying those first two episodes again tomorrow (Friday) at 6/5c and 7/6c, and they are currently still available On Demand.

Now, check out the TV spot and a great clip from the third episode below, along with a couple of trailers for the season. Even if you’ve seen Episode 3 already, and even if you’ve seen it a couple of times, watch it live tomorrow night, and maybe again after that. You never know what you might notice that you missed before. Plus, it’s just that good:
