It's unclear whether Ilian and Octavia are somehow working together during the conclave or if they've fully accepted that they must fight one another to the death for the fate of their respective clans.
What is Echo up to? It doesn't seem like she's preparing to fight in the conclave. But if I had to guess, I'd say she still has a trick or two up her sleeve.
Despite the possible tension, Octavia and Indra share a warm moment together before the battle. Is this the first time we've seen these typically-stoic women hug one another? Maybe.
Indra is presenting her protege with a weapon of some kind — which is a little bit strange, because aren't they on opposing sides? Indra represents Trikru, while Octavia is (as far as we know) is representing Skaikru.
