I still think B & B killed Trip off in an act of petty rage against the fans for not sticking with the show.
"Killed our brilliant show? Well, we'll get you all! We'll kill off your most popular character! There! FU! Try bringing it back after we're gone! NO TRIP! MUHAHAHAAAA!"
I believe that is how it went down.
He was never alive in the first place... The whole point of the final episode was that E was one big holo novel...
If fans could accept that, I could live with it...
