Excellent! Best of the season so far, IMO.
- Nice tie-in to the phasing technology used in "safe"
- cool info about the Amber
Next episode looks veeeery interesting. It looks like the show is picking up the thread about "first people"/ancient technology that had been hinted throughout the show.
Overall I think this season had started out strongest out of the three. Season 1 & 2 both had a bunch of weak episodes in the first half of the seasons. It is the latter parts of the seasons that have been their saving grace. But I am really enjoying season 3 so far. And IMO the alt-verse episodes have been the best ones overall.
