Lucas looked ahead and saw the woman fall to the ground, he stood quietly watching as the two monstrosities came after her, he didn't feel the need to help her but at the same time he realised the fact that she was probably the last person he'd ever see, why not extend the time until death by a few years or days at least, he'd need the company.
Lucas readied the rifle in hand and moved slowly towards the exchange, cocked back the bolt and waited for the correct moment and time to strike.
"...Wait...
...wait...
Trigger."
A bang and a bullet was sent flying towards the two headed monster hitting it smack bang in the chest.  Unsure if it did much he readied another shot, bullets mean everything in this world so he has to be precise.
