It kind of bugged me that Gaal, who can figure out her position from quasars and grew up on a water planet, didn't think to turn the canoe upside down to trap a pocket of air then use weights to get down to the ship. That whole sequence seemed stupid and out of character.

Oh and the prime radiant somehow has enough processing power for two uploaded minds and can suddenly display non-opaque (to people other than Hari Seldon and Gaal) timelines.

The cleons were great though and I love the orbital rings. I wonder how many episodes those will last.
