The Master mans the control center of his TARDIS console. The interior resembling that of the eleventh Doctor, but with more yellow and black to it. He seems to be tracking a potential location of one of his most annoying enemies, River Song. His goal is to capture the companions of the Doctor, who's face he has stolen for his own. Once River was out of his way, the rest should give him less trouble.
He then places his TARDIS Saint James's Park, right by a tree. The Time Lord fixes his suit and heads out, using his sonic to locate River's last known whereabouts. He takes in the scenery around him, remembering when all of the planet had been his and he lost it to the Doctor. The thought disgusted him. The Master Race, capturing Gallifrey with his former Time Lady incarnation, and even turning all the Gallifreyans into Cybermen. He had it all, and he wanted to have the victory he'd always wanted.
As he crosses the street, still following the signal, he seems to get the feeling that he's being watched. He stops at the curb and looks around, his grip on his sonic is tightened, ready for a fight.
