Samantha appears to be playing VR. Her middle head, Mantha, has the headset on. Sam, her right head, has the right controller, and Sammy, her left head, has the left. They’re still getting used to this as they only recently learned that they are just parts of one personality, and partially share a mind, instead of being 3 seperate minds. Sammy appears to notice you first.

Sammy: Guys! Look! Guess who’s here!

Sam: Shoulda gotten his ass here quicker. She grumbles.
