Joe Ga's guess was spot on!
He had previously shot Madeline Parker in the inner side of the forearm, causing a severe laceration that forced the super spy, trained by England's intelligence service, to blend in with the group of hostages, trying to find an opportunity to slip away.
Unfortunately, Boss Joe himself was never the type to show mercy, and with several non-lethal bullets at his disposal, he was now even more unscrupulous.
In front of the terrified hostages, Boss Joe walked up to Madeline, took out a water bottle to rinse her face, then pinched her chin to snap a photo of her face with his phone, and sent it to Tony in the rear.
The result came back quickly. The woman with black hair was indeed Madeline Parker, and the one who had fled on a motorcycle before was probably just her body double or partner.
This kind of situation is not uncommon; the most prevalent example would be magicians' use of "twins" to create many unbelievable illusions.
