This doesn't look like a very pleasant conversation. After Pike was elected Chancellor, he gathered his "troops" and led an attack on Indra's army. Bellamy was all too willing to participate. Is he having second thoughts, after the fact?
Abby and Clarke have been very estranged lately. Abby has hardly seen her daughter in the past three months. Unfortunately, their reunion at Arkadia is not under the best circumstances, thanks to Pike's brutal actions. Abby seems to be trying to calm down or comfort Clarke here. We're sure Clarke is distraught knowing about Bellamy's participation in Pike's attack.
Clarke is looking really distressed as she speaks with her mother, Abby. Has she just heard about the massacre by the Sky People on Indra's peace-keeping force? Clarke is also looking a lot more Skaikru and a lot less Grounder than she has been recently, in this scene at least.
Clarke takes a trip over to Arkadia to see her mother, likely in light of the recent Grounder army massacre at the hands of Pike, Bellamy, and Pike's other followers.
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.
