To shoot the sniper who is up on the catwalk above.
This is when they get jumped from behind by a mook. He addresses Bond by name and then tells him his mission has failed and to give him the access code to the MI6 mainframe and he will let the girl live. So why didn’t the guy shoot them both while he was behind them and they didn’t know. That bothers me but it does happen alot in action movies so… Anyway Bond does not acquiesce to his request and shoots the glass.
Bond says “He bit off more than he can chew.” He then facial scans the guy he sniped and gets info on him. He is a mercenary. Victoria says that they used her father's own weapons against him and asks if he’ll find who did this and kill him. “Yes” he replies. “Good I’m going to help” are her words. They then go on her private jet to Yemen to find the lead they have since the guys were mercenaries from Yemen. They fly away and Bond comforts her the way he is best at...fuckin’.
