Istredd sighs at that hum because he vaguely knows the intention but he doesn't press either. He's not asking for any promises. It's not as if he plans on never speaking to Castiel again himself. He plans on checking in with him soon. It is more coming from a place of concern for Lucifer's life. Once Dean's not a threat, whatever he wants to do is fine.

"Oh yes, I definitely would like us to go directly through the fish market. Really take in the end of the day stench." He smiles and trails his pinkie finger along Lucifer's hand in the smallest of gestures, already walking them toward the portal.

"No, what I want is to go decompress and eventually snuggle in bed with my permanent icicle of a significant other." Decompress from doing something that he didn't want to do, going out and about, and while it was a success overall, he wants to take a breather and release the stress.

"And thank him for making the most of a shitty situation today."
