I'm just waiting for the episode that has them visit a flooded Earth (or similar planet) due to global warming, as they've ticked off just about every other left-wing and environmental issue in the current series.
And the short 2 minute tease of Captain Jack, who is apparently not to returning this season (according to Whovians)... so why have him at all? The message he gave them could have come been from any other source along the way, which would have felt more natural, as that scene felt really disjointed and out of place. I was really looking forward to seeing more of him in that episode and upcoming episodes, but he just seems to have been thrown in to bump up the percentage of minority demographics in this series, which if forced into the flow of a story, will only hurt the reason for including it for making it too obvious.
