Okay, Old Lace dies, and through the connection with her, it means Chase dies too.
But since he's not actually injured he can be revived. But, technically, he's died.
Now I wonder...
Are we seeing a Buffy/Faith moment here? Chase made a deal to sacrifice himself to bring Gert back, right? His life for hers. Well, does that deal still stand? He just died...
So does his loss of life mean Gert returns?
I'll be disappointed if the "one dies, one returns" events are entirely unconnected.
