Pete is later in the break room with Clark when he witnesses Clark using Erin's naiveness to his advantage by telling her he can set her up with a news anchor job but really is just getting her to his apartment for his own purposes. Clark tries to get Pete in on it however Pete rejects he is in any way "pals" with Clark. Pete is later at his desk when Andy confronts Clark about what he is planning to do with Erin.

He is later seen working at his desk and smiles and greets Erin however she is busy learning the germanic tribe language of "Dorthroki" and she growls back a word at him to which Pete appears scared or confused.

Pete is in the conference room where Andy is showing a montage of clips from the office staff's softball season. The staff soon realize it is Andy's horrible attempt at making a "fail video".

Fail!" at Andy when Jim plays the clip of Andy spilling the water cooler all over himself. Pete is later moved onto the work bus along with all the other staff upon Jim convincing Dwight the building is unsafe. He is placed at the table with the accountants.

Pete instead begins making a house of cards with them. While making a wide base for it, Kevin starts ridiculing him for not making it tall. Pete tries to explain that first he has to build a base however Kevin doesn't seem to understand and tells Darryl that he doesn't feel "Pete is the sharpest guy in the drawer" to which Pete responds he can clearly hear him. Creed, Nellie, Erin, Meredith, and Pam later join him and Pete reads the complaints as he places each one on the growing tower. Their goal is to make the tower reach the ceiling. As Kevin tries to place one up there however he causes the tower to fall over. Everyone starts yelling at Kevin however Pete stops everyone and tells them that this entire tower is about mistakes and proves that everyone can make mistakes as their is not a single person present (except for Pam) who has not had a customer complain about them. Pete then gives Kevin a fist bump and says they will just start over. Erin can be seen smiling at Pete. When the tower eventually comes close to reach the ceiling again they realize that they are one card short. Pam decides to step up and make her first customer complaint. She calls one of her clients and makes a "Your Mama" joke however the client's mother had recently died so they complain about Pam as well as drop Dunder-Miflin as their paper provider. Everyone starts cheering and Pete can be heard exclaiming "So long!" however everyone stops cheering once they realize they are cheering over losing business.
