The mental images start flooding his mind as soon as Geralt finishes saying up to him. Which is already awkward by itself, but made worse by the fact that he doesn't know what Dandelion looks like, so Jaskier is picturing a slightly different version of himself wearing the clothes he saw in the wardrobe earlier under this older, kinder Geralt, who is trying to please his bard after making him angry...

"...yeah, well." Woah there, his throat is getting rather dry, what could've possibly caused that? He takes another sip of wine before continuing. "It's the least you could do for him."

He brings his attention back to the stew for a moment, taking advantage of the pause to reassess his thoughts. He didn't lie to Geralt when he told him that knowing about his relationship with Dandelion didn't make him uncomfortable, but it's not like is easy to hear about it either. He can accept it, and be happy for his alternate self, but he doesn't want it haunting his thoughts, whispering mean things about what it means for himself.

"So. A whole estate and your own brand of wine, and of course a daughter. Have you actually retired, Geralt?"

Never thought he would see the day, honestly.
