What I see happening (happened) is that the warehouse was blown up by a nuclear artifact device... so Mrs Fredericks experienced the same fate... it was like she was dying the same way the warehouse was, because of her connection to it.
That is my thinking also, when she started withering away, my first thought was the Warehouse is destroyed.
I'm wondering what Artie can do with the watch, of all the ones I would want to bring back it would have to be HG, but if we're gonna take a darker tone in future eps, I would guess we can't bring back some or any of these people. It was definitely a GREAT season finale.
