After being locked in a bunker for 30 years, it might seem tempting to board a chartered jet to a tropical island with a $1 million bank account awaiting you. However, for Carson, revenge trumps comfort. He decides to kill Harold, Archer’s attorney.
Instead of leaving for the island, he returns to the Monroe family estate. Upon arrival, he abducts Catherine and uses her as bait to lure in Lauren, whom he also captures. Once both women are imprisoned in the bunker, Carson delivers several maniacal monologues and appears to change his plans multiple times.

Carson’s twisted plans leave more questions than answers about his future
His long-term goal seems to be keeping Catherine and Lauren as prisoners, subjecting them to the same brutal treatment that Archer once inflicted on him. He also plans to murder William by slitting his throat, but that seems to be the only additional killing on his agenda.
As for Lauren’s husband and daughter, Carson decides to leave them unharmed, ensuring they spend the rest of their lives wondering why Lauren deserted them. However, Carson’s plans regarding his survival or the future upkeep of the bunker remain unclear.
He seems to have missed some crucial details despite all his careful plotting.
Was Carson Lauren’s biological father?
The most shocking claim Carson makes before being killed by Catherine is that he is Lauren’s biological father. He suggests that Lauren was conceived during the night he raped her mother.
This statement is left unconfirmed, and Catherine and Lauren burn the bunker along with Carson’s body before any DNA tests can take place. Catherine reassures Lauren that she is a Monroe, which is enough for Lauren to accept.
There is, however, substantial evidence to suggest that Carson might indeed be Lauren’s biological father, or at least that Archer believed he was. Lauren had always felt distant from Archer, and her monetary inheritance was less than her brother’s.
Archer also passed on considerable information about Lauren and her family to Carson, possibly allowing him to have an idea of the life of the child he was never meant to meet.
Additionally, Archer’s decision to keep Carson alive and to inform Lauren of his existence indicates that Archer might have entertained the possibility of Carson being her father, even though he never wanted Lauren to uncover this truth.
