Though thinking of Catherine now is already a bit late.
However, as long as holding Catherine, that still gives an extra chip against Ferrari.
From the start of the plan, Wright had people reveal Catherine's identity as an undercover investigative journalist to the gang, which naturally led to the gang kidnapping her.
It can be said that the first step of the plan was very successful.
Without the need to send agents for the kidnapping, they could lure Ferrari to Romania to rescue his sister without exposing any trace—if Ferrari does preliminary investigations, he would only conclude that his sister Catherine went to Romania to investigate gang human trafficking and exposed her identity, which led to her being kidnapped.
Therefore, from the beginning, the CIA was using borrowed knives to kill.
And now, they must find that knife to rescue Catherine, the chip, from under it.
