The Cube sure was creepy, and dangerous because of the lethal amount of radiation all over the place. Hence the hazmat suit you needed to wear to prevent becoming a gamma-powered monster like the ones formerly contained here. However, you feel something stalking you, it's not a person, per-se, but more like...a sentient mist?

The green mist wraps around you and holds you in place, where it then forms into a feminine shaped figure who goes inside your suit. You'd forgotten about Ann Darnell, better known as Vapor! Now she had you, but she wasn't trying to attack you. Instead, she seemed...enamored by you...

"Yes, dear...now Vapor has you...you're protected..."

She sweetly caresses your face and holds you close, a little too tight.
