They're stone tablets, and that's what they've been sent to find, surely? The stone tablets with the symbol on, the tablets that will get them back where they need to be. Sure, it's a little easier than he expected but he's not the one that got grabbed by the greenery.

"You were listening right? These stone things are meant to get us home."

Of course, as they set to examining them, there's writing on the tablets rather than the image of the eye they've been told to look for. Jacob feels his initial buzz of triumph begin to wane as Marty reads the stones.

They do sound like memorials, but they're not grave markers, surely? There no obvious graves here. Then again, maybe the plants don't leave much behind to bury.

"Er-" He begins, as Marty says those fateful worlds, and Jacob turns away slightly, the scratchings on one stone looking remarkably like his companion's name. He reaches forward to pick it up, but they're still tied together, and he doesn't want to make it obvious what he's doing.

"You never did tell me when you were from." He says, conversationally, craning his neck. Yes, he's sure it says Marty. But the rest is still obscured by the stones piled haphazardly on top.
