"Terminator-class is an elite class of secret agent," Turk replied as they took off.  "When there's a mission CIA or MI6 can't risk a normal agent being detected doing they dispatch a Terminator level agent. They're cleared to use whatever tactics are required to complete the mission but the minute you agree to take on a mission as far as the agency is concerned you cease to exist. You get captured and you're completely on your own. If Tyler is deep in Firebrand territory then he's not there for surveillance."
