We kind of went over an example of this with Planes, Trains, and Automobiles.
Neal spends the whole first act suppressing his emotions and trying to play off everything. He has this "just forget it" attitude. This is bottling up sets up the potential.
In the second act, Neal can't suppress things anymore and he starts blowing up and snapping at people and generally losing his sh*t. In this case, the potential is amplified by Preconscious.
In the third act, that clash of Memory and Preconcious allows Neal to start opening up and actually sharing his feelings. His fears about spending too much time away from home and expressing his love for his wife.
Finally, after all of that, we get to the outcome. By exhausting all of his pent up emotions, Neal reaches a place where he can be more considerate of others. This allows him to realize the truth about Del and accept him into his family.
Does that help?
