I didn't even know Rachel and Sam had broken up, but I was really pleased to see all that Michele-Groff chemistry: from the moment Jesse entered the scene, she just lit up!

Nope, that's a previous episode. Montavilla's talking about the one when Rachel and Finn actually have sex (Rachel for the first time, Finn not), and so do Kurt and Blaine. Somewhere in season 4 or 5, I think?

I kind-of-liked the episode too, but what most stood out for me was the
complete absence of Finn references. I mean, really? Hell, there
wasn't even a picture of him on that wall! I'm perfectly fine
with Rachel dating again (I actually wished it, although I can't really picture her with Sam),
but it doesn't feel real…

I rarely read reviews, and the only two times I read yours I didn't really agree with you… but damn you're funny, I enjoyed both!
