"Morning 4587, beautiful day!"

- Peter Yorke to Oliver Queen

Synopsis
Following Oliver's shocking decision to turn himself over to the FBI and reveal his identity as Green Arrow to the public, Oliver has spent the past five months in Slabside Maximum Security Prison. Determined to keep a low profile to shorten his sentence for the sake of his family, Oliver is tested when he runs into old foes.

Goofs

 * John mentions Lyla is working in HQ; however, the conversation takes place in HQ. It is unknown whether John means there is a worldwide HQ of A.R.G.U.S. where Lyla is working, or it is a writing error.
 * The building was later confirmed to be the HQ of A.R.G.U.S. in when the exterior of the building is seen, which proves that this goof is, in fact, a writing error.
