Eli's secret is that he killed his last girlfriend inside his car, and the death card means change. And before the death card was pulled, the Любовь card was pulled out, so im guessing he is going to have a change in his realationship with Claire.
I don't know what Eli's secret is. But I'm dying to know. And I have no idea what the death card means in the video. But I saw on a commercial that he сказал(-а) "This is where I killed my girlfrind." или something like that. But I don't know.
