Author's Notes:
Part three of my drabble series written for Challenge 419 – Survival at tw100.

Summary: Although Jack is in peril Ianto can’t rush.

Ninety-seven, ninety-eight, ninety-nine… one hundred; finally! It wasn’t a moment too soon; Jack was tiring fast, stumbling as he tried to keep beyond reach of the monster’s savage teeth and claws.

Ianto snatched up the Big Gun, checking it and flicking the safety off. Raising it, he took careful aim just as Jack tripped, sprawling on the ground. The huge alien roared in triumph, lumbering towards its fallen foe. If it got its claws on Jack, his chances of survival would be zero, but Ianto couldn’t rush; he’d only get one shot before the gun needed recharging again.

He fired.
