Wasn't it Jamie the one who put him in the coffin in the first place? Then JR helped him with it. But technically the Earthquake "killed" him. But I'm pretty sure Jamie is the one who buried him.
I really hope Spike is Ryan's. I guess when the parternity test is done, I think it is Zach, who demands that Erica tell Kendall the truth about Josh. Because they are brother and sister, Kendall automatically assumes that Madden is the father. What is stupid is why the hell would you use Josh's blood? HELLO, if you are doing a paternity test shouldn't you be testing, oh I don't know, the father, which oh let me think, is supposed to be Ryan.

So stupid!!!
But hey at least AMC is better than Day's now.
