We have a pressing update on the Private Practice season finale.

According to Zap2It, fans might need to prepare for extreme frustration.

For starters, the identity of Violet's baby daddy will NOT be revealed during the April 30 episode.

That's far from all, however.

As previously reported, former Oceanside Wellness patient Katie (Amanda Foreman) will appear on the show. And she'll be seeking serious revenge.

Sources say she blames Violet for her unsuccessful pregnancy and will hold the doctor hostage, demanding that she hand her baby over as payback. Whoa.

What do you think of this storyline? Exciting and suspenseful? Or straining the bounds of credulity?
