I googled it and here's the answer: “She planned to use a sleep patch on the Doctor and then ambush him to force him to take her to save Danny Pink. Danny having been killed in a car accident in the beginning of the episode.”

"Well what do I do now..?"
"Go to Hell."
"Y-Y" *begins to leave*
"Where are you going?"
"Wh-, yo, but you said-"
"We're going to chase after him."
