((This post was too late.))
Anna took the clams and knife alongside a small "Thanks." and just sorta... looked at one with her hand. She'd only seen the stuff in movies and comics and wasn't sure how it'd turn out. Though, as Calen said, crispy meat would probably be the best result. Instead of... whatever sort of goop people seemed to suck up. She was about to try open a shell when the cook asked a question. Her head turned a bit, acknowledging she'd heard him. "Well, for one, close to the fire isn't as quiet as up there. Secondly, although it's not as bad as with sight, intervening objects muffle and disperse the sound more, so being above most of them helps getting a clearer picture a bit. So to speak."
While Calen kept busy with the rest of the meal, Anna started on the shellfish. Mussels. Whatever was the appropriate name. She opened the first one and gave it a good, long stare with the hand holding the knife. It looked... weird, but definitely crunchy. The smell wasn't bad, either, since it was mostly spices. Internally shrugging, she stabbed the lump of meat with the knife and took a bite. It wasn't anything amazing, but it wasn't repulsive in any way, at least. Crunchy indeed. Plus, it was 1) warm 2) edible 3) food, so she wasn't about to skip this meal just yet.
Then the fish (and greens) arrived. Anna once again thanked the cook and partook. First, the greens. Surprisingly flavorful, actually. Maybe that's what wilderness does to stuff? Then came the fish's turn. Still hot, she operated in the same way as the shells: slice a good portion off, stab it and bite. Truth be told, the fish was great. She would've eaten it every week if she could. Which vaguely terrified her, as it would mean she'd become addicted to it if the chef had his usual supplies on hand.
Once she finished eating, she put down the plate - thoroughly cleaned - and waited for the others to finish before speaking, listening to the sounds around them both as leisure and to keep watch.
