If there is a second DLC to Security Breach, I have two ideas what will happen:
One: Gregory or a new character will come/return to the Pizzaplex to rescue Cassie.
Two: Cassie will have to escape from the Pizzaplex with help from Roxy.
This shows the Elevator Ending is the canon one, Cassie survived, and it was The Mimic who cut the wires. If there is a another DLC, what do you think will happen? And what do you of these ideas?
