When we check back in after the time jump, Clarke mentions over the radio that she hasn’t heard from anyone in the bunker, and it’s been too difficult to dig them out from the rubble. Did all of that destruction just come from the death wave, or was there more?

How is Octavia’s leadership going? Gaia looked concerned when her mother brought Octavia out with the spinning wheel symbol on her forehead — will the grounder religion survive without the flame?

Furthermore: What will become of its most devout followers like Gaia? Has Abby killed Kane yet for saving her life against her wishes? Are the clans working together to keep one another alive, or has infighting, disease, or equipment failure lowered their numbers? Are they back to a harsh life of strict rationing and capital punishment like on the Ark, like Jasper and his followers feared? So many questions!

What happened to everyone in space?

We saw that Clarke’s sacrifice worked, and Bellamy and Monty managed to get the oxygen turned on. It seemed like Bellamy and Raven may be the logical leaders of the seven people back on the Ark, but are they? How will Echo handle falling in line behind someone who not only isn’t Azgeda, but isn’t a Grounder? While Murphy and Emori do what’s best for the group, or will their paranoia about their treatment continue to undercut unity, like it did several times this season?

Of the seven who went back to the Ark, there were two couples and three single people. Will Harper & Monty and Murphy & Emori still be together? With Clarke presumed dead and few other options, will Bellamy fall back into old ways and start hooking up with Raven again? Or will he get together with Echo, in a move that is sure to piss off both Clarke and Octavia? Will this show ever mention how everyone is managing their birth control?

What is the deal with the spaceship Clark saw?
