Revelations from Patch 4.3

[Cilia]

Shadowhunter:

Well, I suppose that's pretty explicit.

I figured there must have been a reason they focused on the white mask in the closing scene, and given no Ascian is known to use a white mask there must have been something special about it.

Still, while it does match up with Gaius' old helmet... the "Shadowhunter" could have acquired it from the ruins of the Praetorium somehow, or otherwise acquired one that matches up with Gaius'.

For the record this evidence does push me into the "Gaius Lives!" camp, but the possibility that he's still dead and it's all just an elaborate fakeout isn't something I'm ruling out until we get explicit confirmation.
