Although it makes sense for all continuities to carry the same general plot, I'm holding out for exceptions, as illustrated by the new timeline; Lancelot's bipolar disorder is the obvious example (untreated and thus a terrifying and dehumanizing thing in medieval/base time, wholly understood and alleviated in the primary space timeline, and the various ranges in-between), but also Mordred's history and the internal balance of the story's primary love triangle are notable to me as different among the various timelines.

In other words, I'd miss Merlin if he vanished entirely from the comic, even apart from the emotional hit of his loss as such. Plus, it allows for more play in the mental stagger as the cast jumps between timelines -- [Arthur at his desk considering a treaty or something, in a Merlin-imprisoned-later timeline: "So Merlin, what do you recommend?" ~~~ jumps to: Arthur at his desk in a Merlin-dead-now timeline, head in his hands, staring at a mess of papers: "I miss him so much."]
