Ross soooooo isn't dead, he's a 9 lives guy known for disappearing, he'll creep out of that hole, slither off like a snake, all the while Pete's cracking up with guilt, bang, Ross comes strolling back into the village and Pete's suffering begins.
We're yet to discover what all the cloak and dagger stuff between Ross and Lawrence was all those months ago too, I think it's a case of 'watch this space'...
