I just watched all 4 season 2 episodes yesterday. Kind of glad I watched them all at once, because as mentioned above, they haven't exactly been moving at warp speed. Not a whole ton of mermaid action so far. Levi at the bar was kind of fun. I like the idea that there's no downtime in the ocean. After setting up the sonic explosion problem in the very first scene of the season, it looks like Xander of all people is finally going to be the one to do something about it. Maybe. And yeah, we finally got some of that freaky deaky stuff at the very end of episode 4.
