[He watches Eren with his lips curled in amusement as he tries to figure it out. Mikleo had done the same about a month ago. He was used to the contraptions one could find in Rolance at this point (and Hyland, too)-- the technology had come a ways in about a hundred years. But the stuff here worked so much better, like people with magic and science knew what they were doing.]

I think it's some kind of fire spell. Whenever I see something like this, it's been inscribed somewhere on the inside of the parts.

[He turns up the heat a little and covers the pot, and then he sits beside Eren so he can continue cuddling up beside him. Now that they've established this as a fine and regular thing, he's loathe to give it up.]

That makes sense if you're feeding a lot of people. I mostly ended up cooking over fire pits on the road.

[It'll take a few minutes for the stew to simmer, even though it's covered, so he finds Eren's hand and twines their fingers again. The trembling from earlier has... mostly subsided, a subtle warmth and delight in someone's presence obfuscating the pall of the day. He rests his head against Eren's shoulder again and closes his eyes. He only wants to rest them after crying (and coming close to a second time), not fall asleep, but...

For now, just for now, he focuses on the heartbeat he can detect from here. Without really thinking about it, he matches his breaths to Eren's.]
