Well, that was a predictable ending. 

The identity of the killer was finally revealed on Once Upon a Time Season 7 Episode 15, and I hate to say it, but I was right. Aside from him being Lucy's faux father, he really never had much in the way of a storyline. 

Sometimes, it's good to be right, but in this case, I would have preferred to have been shocked by the reveal. I want to know all the finer details about why he's doing it. 

My best guess is that he's Hansel, and he started killing the witch coven because Gretel was murdered. It would make the most sense right about now. 

It was a little ridiculous of him to have all of the boxes in the back of the car, but it gave us the confirmation we needed to know that he is not to be trusted. 

He was far too nice to Henry to take him seriously. I doubt the wheel being slashed was a random act from someone in Hyperion Heights.

Everything happens for a reason, and the more likely scenario is that someone knows the truth and wants to mess with him. That said, the serial killer storyline feels so random on this show. 

It didn't mesh well with the other storylines that filled the rest of "Sisterhood." I'm all for a good slasher arc, but this one is not off to the most promising of starts. 

Regina: You okay? You couldn't have just stayed at that table?
Ivy: I know ... you were right.
Regina: Well, I would have left too.

The killer reveal should probably have come much further down the line, but that's assuming this storyline is going to be dragged kicking and screaming to the end of Once Upon a Time Season 7. 

It sucked that "Sisterhood" was Adelaide Kane's final appearance on the series. Despite the show's significant flaws this season, Ivy has been a great addition. 

I was so on board to watch her redemption arc playing out, so it's a shame it got cut short so soon. I gasped when Ivy decided to have Ana for her own selfish needs. 

I get that her back was against the wall, and it was coming down to her or her sister, but a part of me felt like Ivy was going to die making up for her sins. 

It was surprising that Regina admitted that she knew how it felt to be manipulated and while she didn't forgive her, she recognized what it meant for a villain to change things up and leave the darkness behind. 

I can't be the only one who would have preferred Ivy's story to end with her banishing Jacinda to another dimension and marrying Henry and them living happily ever after, but we don't always get what we want.

There's still a severe lack of chemistry between Henry and Jacinda, and it was difficult to watch them try to be romantic with each other. 

Henry: Doesn't all this seem weird? I mean, come on, you can't deny how the universe keeps bringing us together.
Jacinda: Because my dinner with Sabine ended up right next door to you.

A 'ship has the potential to sink a TV show, and it would not surprise me if Once Upon a Time would be performing better in the ratings if they had cast someone else in the role of either Jacinda or Adult Henry. 

The conversation between Regina and Rumple was very telling. Rumple is more aware of his surroundings than I first anticipated, and it's clear he's changing his ways. 

He essentially sacrificed his own happy ending for someone else. That's not the Rumple from the earlier seasons of the show. He's always been a polarizing character, and that's because he does not care about throwing people under the bus if it benefits him. 

I'm still on the fence about Facilier. He always seems to show up with those cards when we least expect it, and it's difficult to believe that he'd be anything but a villain.

He may be playing the sweet guy card, for now, to get close to Regina, but he will come up with a way for Regina to settle the debt she now owes him, and it's not going to be pretty. 

"Sisterhood" was one of my favorite episodes of the season. Despite some of the glaring issues, there were a lot of great moments. It's time to bring the core characters back together and wrap this story up. 

Other tidbits from the episode:

• Did anyone else expect Gretel to show up in the present and cause some trouble for Ivy before she left?

• Sara Canning turned in a riveting performance as Gretel, but are we to assume that Nick is Hansel?

• Can we get more scenes of Regina and Rumple together?
