It appears that Jaha and Alie will be working with Pike. Is Jaha content to accept Pike's leadership? Will Jaha and Alie's plans mesh with Pike's goal to eradicate the perceived Grounder "threat"? So many questions!
Jaha and Pike presumably knew one another well on the Ark, where Jaha was Chancellor and Pike was an Earth skills teacher. Now, Jaha is a possibly-deluded messiah of Alie and Pike is basically a prejudiced dictator. How times have changed...
Octavia seems completely distraught after the attack on Indra's army. She was already distrustful of the Sky People, despite Lincoln's pleas to stay and try to facilitate peace between the Grounders and the Sky People. She was right all along.
Kane hangs his head as Abby's back is to him. He and Indra are (or were?) good friends. Odds are he is heartsick at the thought of his people going out to attack Indra and her people. It's even worse knowing that Indra's army was only there to help protect the Sky People.
Octavia does not look thrilled to see Bellamy back in that Ark Guard jacket. We know from The 100 Season 3 Extended Trailer that Bellamy and Octavia are due to have a serious falling out. It appears that Bellamy's decision to support Pike is the act that drives the wedge between the Blake siblings.
Seems that by putting a Ark Guard jacket back on after giving his back to Kane in "Watch the Thrones," Bellamy is accepting Pike's leadership all over again. Sigh. Oh, Bellamy. We hope that's not the case.
Bellamy and jackets are significant. He wore it as a guard back on the Ark, before he attempted to assassinate Jaha. Kane gave it to him once the remaining Arkers joined the Delinquents on the ground. Now, Bellamy gave it back to Kane as a symbol of his choice to throw in with Pike. And now that Pike's in charge of the Sky People, he's giving Bellamy back that same jacket. Bellamy's gone through a ton of change, is what we're saying.
Pike: This morning on the muddy field our people paid tribute to those who have been taken from us by sending a message to the Grounders: "This land is OURS now! Resist and you will be met by force. Fight and you will be greeted by death." Today is a new beginning. Mark it down, remember it -- just like the Grounders will remember it.
