The team continues to work on pounding the concrete floor in the storage room during PI. Sucre worries over how they are going to dispose of the concrete fragments. Michael tells them to hide the fragments one piece at a time. They take the pieces out, littering and hiding them all over the yard. After Michael walks off, C-Note picks up one of the concrete fragments half hidden in the yard. As Michael and Sucre walk back to their cells, Seth jumps off from the second tier and hangs himself. Michael looks horrified.
Michael tells Lincoln of Seth's suicide and how he felt responsible for his death. Lincoln tells him that it's not his fault and that he had to keep the escape plan safe. Michael relays that their mother taught them better, "When a man is down, you give them your hand." Meanwhile, a new inmate, David "Tweener" Apolskis tries to fit in. However, neither the black nor white inmates want to associate with him. T-Bag uses this opportunity to intimidate Tweener and suggests that he could be his new "friend". Tweener tells T-Bag to stay away from him. T-Bag is annoyed by his noncompliance.
Dr. Sara Tancredi inquires Michael's insurance company about the cost of his medical treatments at Fox River. She finds out that he had psychiatric insurance. Sara visits his psychiatrist who informs her of Michael's psychiatric condition. Michael has low latent inhibition and low self-worth.

After Sara learns this, she becomes more perplexed by who Michael is.
Michael notices Tweener's distress and decides to intervene. He hits T-Bag
