What episode?

When Sully is helping Michaela lace up her corset, she said she remembered the first time she saw him in a suit. He said he remembered the first time he helped her out of "this rig" and Michaela added that bandage scissors were involved. I know the first time she saw him in a suit was on her birthday in the first season, but which episode did Sully use bandage scissors to cut her out of her corset?
