At the 2nd hulk out, you can see the wires used to pull and hurl the driver's side door halfway across the street when the Hulk exits the car.
Alias: Not given
Diana Muldaur also played David's sister, Dr Helen Banner, in the season 3 episode Homecoming.
In this episode she played a nun and therefore is addressed as sister. Perhaps an in-joke to her earlier appearance as David's sister.
