User blog comment:Evil-Tree/Potential for Saren in ME3?/@comment-1341687-20120207210215

Not too much of a stretch. We know that clones are possible, since we have seen it twice with krogan. If the Reapers were in contact with Sovereign during his work with Saren (I think we can assume this since Harbinger was controlling the Collector's before even these events) then it all seems highly plausible. The real question is, can they do it in such a way that won't leave fans upset about how/why he returns?
