1.)

(Jack and Karl return to the cabin. Jack's eyes glint unnoticed in the shadow and Karl grasps at his own throat dramatically.)

KARL: It was like everything out there wanted my blood!

2.)

(Jack makes a mega-droll expression and hand gesture, and Karl is like whatev-ish.)

JACK: Not everything...

KARL: Anyway, I'm bloody freezing!

3.)

(Jack has a vaguely saucy look about him.)

JACK: I know how to warm you up...

4.)

  (A short while later, in a view from behind, we see Karl is swaddled in a
blanket and Jack has built a fire. They are cozy on the floor in front of it.)

KARL: Hm, yup, that worked.

5.)

(Jack lets himself into Karl's blanket and looks at him gently. Karl is into it.)

6.)

(Swathed more fully in the blanket, Jack and Karl begin to kiss.)

7.)

(As Jack and Karl continue their makeouts oblivious, a random light reveals to us the image of their
  stalker outside the window. It's a man-shaped creature with a skull mask on face and axe in hand.)
