Jaha and his City of Light disciples have vacated Arkadia by the time our favorite delinquents make it back there, but they left something behind that does not look friendly. Get ready for a little scare on The 100.

It’s taken a while, but our favorites are finally back and working together on The 100. When Clarke, Bellamy, Jasper, Monty, Raven, Octavia, and Sinclair arrive back at Arkadia, it’s been abandoned by Jaha and all the innocents that took the City of Light chip. That could seem like good news, since that would mean that there isn’t a fight to take back the fort, but it seems that Jaha and ALIE may have left something behind, and it isn’t a welcoming committee.

Despite the apparent demon haunting Arkadia, we’re hoping to see a few of this brave band face their own demons. Jasper is still harboring one hell of a grudge against Clarke, Monty will undoubtedly be dealing with the aftermath of killing his mother, Bellamy is haunted by the lives that were taken due to some dumb choices on his part, and Clarke is definitely still feeling the loss of Lexa. Something tells us that they’re all going to have to find some sort of peace with their current circumstances in order to defeat whatever is stalking around Arkadia.

While our main group is taking back Arkadia, Murphy will be surprised by a meeting with Jaha at Polis. Apparently Jaha doesn’t have enough followers for his new City, so maybe he’s going to Polis to see about converting more of them? Or maybe he wants to let the Grounders know that their leader hasn’t been fully crowned yet, since Clarke ran off with the A.I. We know that ALIE wants ALIE 2 in order to destroy it. We know the upgrade is the only thing that can stop her, and maybe he can get the Grounders on the hunt for Clarke as well as gaining some new followers for the City of Light.

There’s a lot of things currently unsettled on The 100. In addition to the craziness going on in Polis and at Arkadia, we are eager to meet Luna, as she has connections to both Lincoln and Lexa and seems like a possible ally in the fight against Jaha. Whether we meet her this season or not, she has become quite the legend on the show.

What exactly do you think Jaha and ALIE left behind at Arkadia on ‘The 100’?
