Obi-Wan's eyes widen in surprised delight at her sauciness, following Padmé easily even as the path becomes more rustic and steep.

"Well, that's fortunate," he says a few moments later, drawing near to her shoulder, "because I will most assuredly go white long before you." Age has never bothered him in companions before - and it doesn't now either, Jedi have naturally long lives thanks to their strong connection to the Force - but every now and then he is reminded that Padmé is over a decade younger than him. She's mature, and compared to Anakin, only 5 years her junior, she might as well be middle-aged. Being long-lived doesn't mean he won't continue to look his age. For all he knows, he'll end up looking like Master Yoda.
