So... ten years. Damn. To be fair, it's less of what he would expect from the father of a teen girl. He had her at his twenties, that's hella young in this day and age (and accident maybe? Geralt isn't wearing a ring, that's one of the first things Jaskier always checks). But hey, half your age plus seven, right? Jaskier fits the math, and they're both working adults with lives of their own... The spirit is what matters!

(His sister is going to hate this.)

"Thirty-eight. Bloody hell - my compliments to your working-out routine, good sir." He grins then, hands and legs moving to get Pegasus into a walk again. "This baby face can play this game as well. Let's see how old you think I am. I'll even give you time to figure it out, Master Equestrian."

And with a wink, he's off, asking Pegasus to canter again as he starts singing...

The fact that song happens to be Stacy's Mom is just a coincidence.

Clearly.
