Here's a breakdown of the events:
* Greg wants to be seen as "cool" by Rowley: He tries to impress him with his "cheese touch" immunity.
* He fails miserably: Greg tries to convince everyone he's immune to the cheese touch, but the others expose him, resulting in him being "touched" himself.
* The cheese touch is contagious: Greg becomes convinced that the cheese touch will spread and ruin his life.
* He tries to escape: Greg attempts to flee the party, but Rowley gets caught in the crossfire and ends up being "touched" too.
* A moment of realization: Greg realizes his foolish actions have made Rowley a social outcast as well. He learns a valuable lesson about friendship and understanding that true friends don't try to make each other look foolish.
This climax serves as a turning point for Greg. He begins to realize that trying to be cool doesn't always work and that true friends are worth more than any social status. It also highlights the importance of empathy and understanding.
