Fantastic Four Headquarters:
Ben Grimm, the THING is walking to the kitchen,thinking about making himself some tacos.
He sees Johnny Storm, The Human Torch’s door slightly open and thinks about asking him whether he also wants a taco.
He walks to the door and opening him, sees Johnny naked on his bed, with a few semen stains in front of him. Unbeknownst to Ben, there also seems to be another semen-stain on the wall, behind the now completely open door.
Seeing Johnny like this, he says, “Jeez Johnny, lock the damn door if you want to get off! What if your sister saw you like this?”
Ben closes the door and walks away.
Suddenly the stain on the wall seems to move, as if it wasn’t on the wall, but on something, or more likely, someone invisible.
“Do you think he knew I was here?” Came the voice of Sue Storm, the invisible girl.
