Definition from Wikipedia:

Surprise is a brief emotional state experienced as the result of an unexpected event. Surprise can have any valence; that is, it can be neutral/moderate, pleasant, or unpleasant. If a person experiences a very powerful or long lasting surprise, it may be considered shock.

This definition gives me an idea for this brief, The 3 frames would divided according to this definition. 

The first frame is about the instant surprises or effect of the surprises, the last frame is the shock or the long lasting effect caused by the surprise and the middle frame is about the other emotions followed with the surprises.
