So this is something I've been confused about for a while. Who is Lord English? Like I get that it's Caliborn grown up, but didn't we see Mr. Vanilla Milkshake turn into him in [S] Begin Intermission 2?

On this page we see that Arquiusprite, half of Gamzee, and Caliborn are sucked into Lil Cal. Doc Scratch was created ectobiologically from Lil Cal and a white cue ball. So when he died Lord English emerged from his body as a fusion of those three guys.
