"Oh--!" Clementine hears that screech and see's those teeth and damn it, why did they have to be fast mutts this time around? She's pushing herself as fast as she can with her shorter stride to keep up with the two men, all of them hampered by having no idea where it was they were going within the base.

There has to be somewhere safe up ahead, somewhere they can hide from these things, they just have to get there first. What are the chances the mutts can actually open doors? She opens her mouth to say so when Nick screams.

Clementine puts the brakes on immediately, skidding to a halt and almost falling as she calls out, "NICK!" No need to be quiet, not when the mutts are already on their tails. "Oh God!"

She doesn't think, just grabs what looks like a broken panel off the floor and throws it at the alien that's about to kill her friend.
