Harley has no idea what a Star Wars ship would look like if she came upon one covered in snow. So she just stares at the large vessel with a curious look. She gestures to Palmer and Furiosa to get down low, just in case (which is also a little ridiculous considering she is wearing bright pink and still very visible).

With the boarding ramp down... Harley doubts there would be anyone still inside. After all, who could survive being blasted by the cold winds?

"Okay... I am going to go first. Palmer and Furiosa stay here. Furiosa give me cover fire if anything happens."

She pulls her sword from the sheath on her back. And with a brief moment of concentration, the fire sword comes alive with flames licking the metal. This should give her plenty of light as she approaches the opening of the ship.
