It's obvious from Clarke's expression that she hasn't bothered to read her menu. Honestly, she wanted Markus' company more than she wanted food, so the pairing part of it has gone out the window. It just—it seemed like a thing. A thing to enjoy.]

Praimfaya ... It's a word in Trigedasleng, which is the language of the people on the ground. [Of the tree people, in theory, but she knows that every nation speaks it. Clarke has learned a lot of their history, but never as much as she'd like. If she had been given more time with the Flame, she'd know. But that's neither here nor there.]

My ground. The ones who somehow survived the apocalypse. It means the first flame, the point when rebirth happened. There's a chance it's connected to a cult that believed that people would rise from the ashes. [This is a time when she wishes she had spoken to Jaha about it more in theory than in terms of trying to find a solution. Maybe if she'd been in the bunker with him. Maybe.]

Somehow it's come to refer to the act of the planet burning itself. It feels more encompassing than, well. "Nuclear reactors broke down."
