Cringeworthy moments aside, I liked this episode. I thought the flip of Zoey being the one doing the singing, and that it was for real (not in her head) was well placed as to where the show is right now. I also loved that we got the few glimpses into her "real" voice and "real" dancing abilities. Did anyone else notice that during Crazy when we were in Zoey's head with her, her hair was perfect in all scenes. And when we saw the "real" her (as Max did) her hair was an absolute mess? Just like it would be if someone were doing all that dancing in real life. I thought that was a cute detail.
I do not see Leif as a predator. I see him as a schemer. Joan isn't "prey", but she is the target of a con job. I don't think his Plan A is to scream sexual harassment, I think he just wants to be teacher's pet and usurp Zoey for as long as possible. But, I'm sure a sexual harassment claim is his Plan B, for when Plan A comes to an end.
I'm also curious as to how they'll handle Mitch and his presumably inevitable death. I don't see a miracle cure coming, since they've identified this as a real life disease. Unless it's been a misdiagnosis all along, and instead he has an operable brain tumor, or something like that. But that seems like a big cop out for this show.
I think there's continuity errors with Simon. Zoey confessed to her mom that she liked him, so this whole "I never knew how I felt until I sang" is just weird. She had one big ol' crush on him from day one, and she knew it. That's why I Want You to Want Me makes sense - he's a hot guy (with a hot girlfriend/fiancee), she's a nerdy girl, and she just wants to be wanted by the hot guy she has a crush on. And that's why I understand Max being crushed - yeah, she's got the feels for him, but he's not the hot guy that she wants.
And finally, I really missed Mo this episode. It would have been great to have a Mo/Zoey duet. And, as Zoey's original confidant, Mo should have been looped in on this new twist in Zoey's powers. Their absence was conspicuously weird.
