@drrodneymckayphdphd here we go! Super cute prompt, thank you!
Jaskier has studied astronomy, he knows the constellations, the old songs and myth that made them into being. He knows the brightest star in the sky, he knows of planets and lunar cycles and can point them out on a map, or on rare bright occasions, in the inky blackness above.
That doesn’t mean he won’t ask Geralt to point out the Traveling Star, the guiding light. That doesn’t mean he won’t play dumb until Geralt bodily moves him to stand right in front of the Witcher, back against chest, so that he can follow his line of sight.
If Jaskier leans back a little, and accidentally catches Geralt’s other hand with his, lightly tangling their fingers together, Geralt doesn’t say anything about it. He just murmurs close to Jaskier’s ear, accepting the weight and pretends he doesn’t know Jaskier knows more than him of the stars in the night sky.
