Well actually in reference to the review..
"He looks vulgar and indulgent in his recliner, a jag-off nobleman luxuriating in the spoils of his kingdom, like some kind of… king? (NO. Not yet, at least.)"
And then later Maggie basically calls him yellow…
Yellow king…

Maggie also calls Marty a "coward" which has always been associated with the colour
yellow.
"Nobody calls me yello…..Nobody!!"
