User blog comment:Woohoot/Future Lucy and future Rogue timelines/@comment-904888-20130607113949

I have two theories, but the main one will be that the events of the current Timeline with f-Lucy and f-Rogue (possibly f-Shadow), the events may be exactly what contributed to the current timeline.

To put it simply, it is evitable, everything they do now will wound up putting the events leading to f-Lucy etc timeline. I suspect that f-Rogue is the one that casted the 'Shadow' personality on his past self (evidence points that way, in 333, Shadow knows that Rogue is becoming the king, which an external entity would unlikely to know, unless that came from f-Rogue himself).
