Actually, one of the writers said that Blair was still alive and under Nephilim control. It's in the CIC archives somewhere.
Er...
The closest I've ever seen to that idea is that there is fan fiction speculation to that extent. And seriously, such a view would be absolutely preposterous. The gate destruction cut scene makes a few things clear.
1.) Blair was attacked by a Nephilim inside the tower just as the gate exploded.
2.) While the gate may exist on both the Kilrah and the Nephilim sides of the worm hole, the physical structure that was on the Kilrah side of the wormhole remained on the Kilrah side (albeit wrecked) after the explosion.
3.) Blair's craft is visible from the tunnel where he was attacked.
From this we can gather a few things. First of all, even if he survived the explosion of the tower, the Nephilim probably killed him (at the very least, having it land on him would quite possibly do the trick, and if it didn't, he's probably got a few broken bones - that was a big Nephilim). Second is that from the presence of Blair's craft, we can infer that he is on the Kilrah side of the wormhole (and we don't even know if there is a physical structure on the Nephilim side of the wormhole). Third is that everything that was on the Kilrah side of the wormhole before the explosion was still in the Kilrah system after the wormhole collapsed. Whatever is left of Blair is still in the Kilrah system, which is Confed controlled.
i.e. While it is conceivable that Blair somehow survived both the Nephilim and the explosion, he is still in Confed space, and thus NOT under Nephilim control.
About the only way I can see that he could be under Nephilim control would be if the Dula VII raid only retrieved a clone of Blair, and not the real deal - and quite frankly, there's no evidence to suggest that.
