Knowing they just had only 15 minutes to finish everything and get out of there, with the sign given by Irene and Bennet now not focused on him, Victor continued to throw the smoke grenade that he now held in his hand towards Bennet's hand, which was the one holding the remote control of the bomb that he plant around the building.
The target was right on Bennet's wrist and even caused the remote control to fall to the floor as Bennet did not have time to do anything because he was surprised by the smoke that suddenly appeared there. Without wasting time, Irene continued to run towards Bennet and started attacking him in droves even though it was hard to see now due to the smoke.
Creation is hard, cheer me up!
