It would seem Xigbar's nasty habit of eavesdropping was infectious, considering the small fact he had paused just before entering the kitchen where the two were talking to listen to their conversation for a bit instead of just continuing on inside and run the risk of them going quiet and possibly departing to take their conversation elsewhere.
Kokoro? Ah yes, that meant-- an interesting idea that, backing up the most obvious portion of the boy's heart before doing what he did to remove the original. He'd have to have a small talk to Xigbar about that later perhaps.
Heading on instead the kitchen as the conversation wound down, he headed to attempt making dinner for the night, one hand checking the coat pocket to make certain he hadn't forgotten to bring a potion with him for when he aggravated his bad shoulder getting things out of the cabinets. In all honesty he likely shouldn't be doing anything to hinder the remaining healing time but one got rather sick of junk food or take out after a time.
