Barb Larvernor

Barb Larvernor is the enthusiastic scientist who helps Curt throughout the play, providing him with cool gadgets and gizmos he can use on his missions. She's also there when he needs someone, although her help is often not appreciated. She has feelings for Curt, and these are consistently shown through her words and actions from the start, when she has to correct her wording of how she was worried slightly, to the end, when she misinterprets Curt's words as him somehow hitting on her.

In Act 2 Part 3, the Informant asks if she's been with a woman before, to which Barb responds no and starts leaning in as if for a kiss. This is broken by the informant puking on the floor, but it raises the question of Barb's sexuality. Based on what we see, it would be safe to assume she is bi-curious, although we have no way of knowing for sure. This means that if Barb were to ever know about Curt's sexuality, she would most likely be supportive of him.
