Let’s start with the fact that Alan Tudyk, who played the pilot Wash in Firefly, is driving the boat while Fillion does his best captain’s pose.
Let’s hope things didn’t get too nostalgic, and someone decided to launch a harpoon!
Considering how many fans are constantly begging for this show to have a reboot of some kind, it may still be too soon.
Considering that photo credit Nathan Fillion gives belongs to Tudyk’s wife Charissa Barton, it’s not all that unusual that a man is driving a boat he owns, but then that caption teasing the reference to the show really gives it away.
