The Pretty Little Liars production designers clearly have an eye for detail, and apparently there's something extra cool for us to watch out for on tonight's episode, Season 3, Episode 18: "Dead to Me."

Read spoilers at your own risk! For more on Wetpaint Entertainment's philosophy on spoilers, click here.

As the sneak peek photos show, part of the episode will take place in a mausoleum, where Ali's remains are being placed.

We should all keep our eyes peeled, because production designer Fred Andrews tweeted, "'Dead to Me' #pll Tuesday - look for special names on the mausoleum walls! ;) really proud of this episode!"

So, will the "special names" be clues to the mystery, or just some fun easter eggs? Either way, we'll be watching closely.
