"The 100" season 3 episode 12 spoilers had revealed that Arkadia might be a ghost town. The Sky Crew's home was bound to be the focus of the episode that aired Thursday.

According to Melty, the sneak peek of the series unveiled that a lot has happened since Jasper and Clarke threw the town in a panic. The "merry criminals" will actually find that every single person has left Arkadia, making it as a ghost town. 

The trailer begins with Monty driving the jeep through the entrance gates, whilst Octavia, Clarke, Bellamy and Sinclair flank the vehicle. They're all carrying weapons, and it's clear that they expect resistance but they are surprised to find that no one is in town.

Here's the full synopsis of the episode entitled "Demons," courtesy of Futon Critic:

"JAHA RETURNS TO POLIS - Jaha (Isaiah Washington) returns to Polis, and Murphy (Richard Harmon) has a surprise encounter. Meanwhile, Octavia (Marie Avgeropoulos) uncovers a clue. Bob Morley, Devon Bostick, Lindsey Morgan and Christopher Larkin also star."

However, other reports are questioning whether his arrival will be welcomed wholeheartedly or not. Murphy already knows the truth behind the artificial intelligence "ALIE" which is responsible for the world's destruction.

In addition, the artificial intelligence tricked the Skaikru by deceiving them that they could have control when they seized the chip. "The 100" season 3 episode 12 aired on Thursday, 9 p.m. on CW.
