A one-eyed jack is, in a standard deck of cards, the jack of spades or the jack of hearts, both of which are seen in profile (and thus only one eye is seen). The popularity of cards and the somewhat macabre nature of the phrase have led to its use in popular culture.
These are mostly throwaways; I took them last night to use up the last of my battery’s juice so I could recharge it today. For being quickies, they actually turned out rather good — color’s much better now that I’ve white balanced with Joce’s hair in mind, and the connection between Dom and the one-eyed jack was too good to pass up. I’ll probably take more in a similar vein in the future.
(For the curious, a larger version of the second image is currently my desktop wallpaper. XD)
