Another option
If Eno was planning to bring back Vorden and Raten and not by bringing them back into Sil's mind, Quinn and the others were starting to think of what Eno was exactly planning to do. That's when it hit them, that maybe Eno already had something in mind.
After talking to Fex, and learning of what happened to Innu before Quinn had arrived to the others on the desert that day. Quinn realised that just as Eno had said, three people that looked identical to him had appeared in front of each of them.
At first, Quinn thought maybe they were using an ability of some sort, but it seemed to be something beyond that,
'Does that mean that Eno is able to create clones, or something similar with his ability?' Quinn thought. It certainly wasn't out of the realm of possibility. After all, Borden was created and he was nearly an identical copy of Vorden before he transformed into a Dalki and used up all his power.
