Ford thanks the Powers That Be that he's got good reflexes - he catches that gun rather than dropping it, or worse, fumbling and accidentally blowing his foot off. He's quick to turn around and level the gun on the monster chasing them down. He doesn't flinch at the sight of it, doesn't get that very human chill down his spine upon looking at something that just Should Not Be.

He's seen worse, far worse. The shapeshifter doesn't have a form in its repertoire that can scare him as bad as the things that have been floating around inside his head every night ever since he dismantled the portal.

Ford holds his breath, takes aim, and fires.

Green fluid sprays out the back of the creatures head, its body thrashing in agony as it shifts erratically, gaining and losing limbs and size without rhyme or reason. It staggers, lashing out wildly in the hopes of hitting something. A long, clawed hand swipes out at Stan, and a thick, lashing tail damn near takes Ford's head off before he ducks out of its way at the last minute.

"Now, Stanley, now! Before it regenerates!"
