Beetlejuice reached into his jacket and dug around for a battered business card. While he'd discovered immediately upon arrival he was visible, his curse was still in effect. It made introductions awkward, but, he'd found some ways to work around it.

Showing his card was the easiest route. (Although, not as much fun as charades.)

The card simply read: Betelgeuse in a normal font. Below that was a hand drawn doodle of a beetle and a juicebox.

"Likewise new. Nice to meet you, Gwen." It might be the only time he got her name correct.
