Q & A: "Cobb's foot chase sequence at Mombasa"
Q4.1) Was this a dream?
Answer: No. If it was a dream, then Eames would be just a projection. Why would Cobb enter a dream to recruit someone who would be part of the team from the start i.e. reality? Conversely, if it was a dream, Cobb would not have panicked when he saw agents coming to kill him; if Cobb was killed, he would merely wake up in reality (and not in limbo) since it could be assumed that heavy sedation was not used for single-level dreams.
**There are arguments that this sequence could be a dream. See Section 4 (Theory #2) for an explanation.
Q4.2) Who and why were the people chasing Cobb?
Answer: They were agents from Cobalt Engineering, Cobb’s former employer. Cobb was wanted dead because of the botched extraction mission on Saito.
Q4.3) Why was Cobb at Mombasa?
Answer: To find and recruit Eames, the Forger, who would be very useful for the inception mission.
