Steph isn't moving. She's going to wait right here. Babs will come back when she realises Steph's not following, right?

Oh, wait. Babs.

Steph jerks herself into motion, hurrying after her to grab the arm of her chair. In theory, this is enormously rude, will probably result in her getting an electric shock, but will turn Babs around.

In practice, her arm just goes through the chair as if she isn't there.

"Babs! Stop!"
