[ he does notice red wing, and that's where castiel's attention stalls for the remainder of the conversation. the bird's head tilts one way, and cas follows, then the other, like they're playing a mirroring game. when sam emerges back into the living room, he's still there, with one of sam's trinkets still in hand, forgotten in favor of the avian friend. ]

No, I’m never hungry, but I appreciate the effort for hospitality.

[ very thoughtful of you, sam, if he had any use for bread he'd take you up on it, but given the state of medieval economy and food scarcity, he'd rather not take from sam's provisions frivolously. besides - molecules, it's all just molecules to him. the new conversation's enough to pull him from communing with the falcon (who was probably ready for the weirdo to stop staring at it anyway), and his interest returns to Sam, eyes finding him with a small, polite smile. unfortunately, still clutching the trinket, as he might've forgotten where he picked it up by now. ]

Thank you for welcoming me into your home. It seems... nested.

[ well-loved, warm and comfortable, suited to him. it seems sam's made the best of an unexpected relocation and created a proper home for himself. humans have an admirable talent for that castiel's never quite been able to grasp. even the brothers turned the impala into a familiar safe haven while on the road. ]

If there’s nothing else you feel I should know beforehand, yes, I suppose we could... get right into it.

[ copying the phrasing others use typically helps with his lack of people skills, or at least, cas thinks it does. there'll probably never be a day he's completely without some element of off in conversations with strangers. ]
