Regarding the Manhatten-Daleks episode: from GQ

It concerns a plot to create Dalek-human hybrids and features the Pig Men, amiable sorts with porcine faces and human bodies. It concludes with typical restraint with the Doctor climbing the Empire State Building while lightning clashes around him. Trapped in the sewer is a group of humans, including the Doctor's new assistant, medical student Martha Jones, played by Freema Agyeman. Daleks have them surrounded."Silence! You will form a line! Mooove!""Just obey," Martha shouts, of her companions."The female is wise! These are strong specimens! They will help the Dalek cause!"A Dalek extends its sucker, scanning brainwaves."Low intelligence!"And there's an interview with David and Freema. Do David and Sophia really get drunk and dance the salsa at Billie Piper's house? (He's not saying.) A year ago, Freema was working at Blockbuster Video. Good stuff.She describes the Doctor/companion chemistry thus: "She's keener than him."
