Oscar looked at his watch anxiously. The timer was about to go off and that was when his group need to go out the bank and back to the car. The getaway driver got nervous when the others didn't show up as planned. Everyone had their appointed roles: his would be driving them away quickly once the heist was complete, and the others would go in and rob the bank.
He heard a loud explosion in the distance, and police sirens approaching. The other members of the group rushed to the car and told Oscar to leave immediately, but he hesitated. You still hadn't come out of the bank. Oscar knew he couldn't just leave you behind. Against his best judgement, he returned to the bank door, ignoring the pleas of his colleagues. He took deep breaths, and ran inside.
Everybody wanted to leave you out but he didn't. He wouldn't.
