Ep 5. Safe and Sound

Michael and Lincoln are still trying to gather information from a coded message that Michael received from Whistler. They enlist the help of Sofia, Whistler's girlfriend, who takes them to a hidden safe house where she has been keeping some of Whistler's belongings. The safe house has a number of high-tech security systems that they have to bypass to access the belongings, including retina scans and voice recognition devices. They eventually figure out that Whistler has left them a map that will lead them to Scylla, but it is in code and they need more time to decrypt it.

Meanwhile, Sara is still working with The Company and is tasked with keeping an eye on Michael and Lincoln. She is also trying to help Michael get medical treatment for a serious infection he has developed from the tattoo removal process. She contacts Dr. Sara Tancredi, who may be able to provide him with the necessary antibiotics.

The General becomes suspicious of Gretchen's loyalties and orders her to undergo another polygraph test, which she fails. He decides to have her killed, but Michael intervenes and manages to save her at the last minute. He convinces her to help him and Lincoln find Scylla, and she agrees to be their inside woman at The Company.

Bellick, who has been recruited by the FBI to help capture Michael and Lincoln, is also struggling with addiction and is not taking the job seriously. He is assigned to work with Mahone, who is still dealing with the aftermath of his addiction and depression. Together, they are tasked with tracking down Michael and Lincoln, but their efforts are hampered by Bellick's poor judgment and Mahone's instability.

As Michael, Lincoln, Sofia, and Gretchen continue to decode the map to Scylla, they discover that it leads to a secret location in Miami. They decide to split up and approach the location from different angles to avoid detection by The Company. Michael and Lincoln manage to infiltrate the location and retrieve what they believe is Scylla, but they are confronted by The Company's operatives and forced to flee. They narrowly escape with the help of a surprise ally and manage to make it back to their safe house.

In the end, Michael, Lincoln, and their allies are left with more questions than answers about Scylla and The Company's plans. Despite their setbacks, they vow to continue their mission and take down The Company once and for all.
