You can still salvage this, Heller.  Here's how.

S5E2 ends with Jane drinking belladonna tea, so he can see his daughter again.

Everything since then has been Jane's hallucination.

It's the oldest trope in the book, and it's still better than what you gave us last night.

Sad thing is...

I care about these characters and will likely watch the rest of the season anyway. 

But will I ever let myself do this again, with any series?  No.
