In my opinion, I do think the last scene with JJ and Emily in Paris is unnecessary.

It would have been much more emotionally powerful had they ended it at the funeral scene. Leaving it ambiguous, with nothing more than Hotch's and JJ's furtive looks to clue us in. It would be maddening and sickeningly depressing, but it would have left a greater impact.

Oh well. I'm not going to continue to complain. They probably wanted it to end with a slightly positive (though bittersweet) note: Emily's alive and in one piece (can't say much about her fingernails though) and she's in Paris!

The way she said "Thank you." It was so quiet, small and distant. Almost like it belonged to someone else. Less like Emily's. It fits though. Lauren Reynolds is dead. Emily Prentiss is dead. She has a new identity now, to live on. To fight on.

Wonder if she's out there, hunting Doyle?

My heart aches, that's this would likely be the last time we see here - but yes, goodbye Emily.

Au revoir et bonne chance, Emily. Bien fait.
