The butterfly theme refers to "the butterfly effect" used in chaos theory, where a very small change in the initial settings may create a significantly different outcome. While the change in this episode is where the butterfly lands, "the very small change" is figurative and does not really have to be butterfly-related. See more
In the second variation of events, just after Carla complains to Turk about not standing up for her, she goes to walk 'away' from him, but when the scene cuts to another angle, he is on the other side of her and she has to walk past him to leave. It's a re-use of the first variation of this event. See more
