Continuity mistake: Right after Charlotte leaves to dance with Gordon Carrie's right arm is raised or not depending on the angle.

Visible crew/equipment: When Carrie crosses the street with Miranda after Miranda's sonogram, she turns while talking and a mic pack is visible half in the waistband of her dress.

Continuity mistake: After Miranda uses the sonogram as a coaster she holds it from the lower part, but when the angle changes she is holding the upper part.
