First it's just a normal trailer. Zac's in a normal shirt. THINGS ARE NORMAL.
Then he's in another shirt and things are still just moving along. Nothing to see here.
Then all of a sudden at least the top part of his shirt is off.
His naked arm has now made an appearance.
Oh my god what is happening.
OH DEAR THE CAMERA IS PANNING AND HIS CHEST IS FULLY NUDE.
OH LORD. *FAINTS* *RISES* THAT IS HIS BUTT.
ZAC IS EXPOSED ON THE TOILET.
He is holding himself up and moving his fingers and NOTHING IS THE SAME.
You have just started breathing again and then all of a sudden there he is, shirtless in bed.
And he continues to move his abdomen up and down while you grasp for air.
And yes it's great but this is all that matters right now.
