With only one more episode remaining this season, "Devil in a Blue Dress" really proved that this show should get a chance to return next season.

It began with Anna's plan to build Concordia in its first stage of construction. 

If it wasn't for Sid, the Fifth Column would never have been able to put together that Concordia is a landing site for motherships around the world.

This boy genius even came back at the end to show his fellow Fifth Column members that the Visitors already have their other motherships waiting in the clearing to invade. He deserved more credit than his fellow mates had given him. It seemed like throughout this season, Sid had been picked on for being a dork, but that dork has kept The Fifth Column right on the Visitors' toes.

When Sid pressed the button to destroy the blue energy, I really thought shit would hit the fan. Alas, Ryan was there to deactivate it. This whole scene made me feel uneasy because I truly believed that if Sid would have completed the mission, Anna's plans would have been foiled.

I don't think it was a ploy when Diana pointed out to Marcus that she is not here to create peace, but wanted what is best for their kind. Diana desperately wants to be ruler again and won't stop at anything to become Queen, even if it means that she must become allies with the Fifth Column. 

Both Diana and the Fifth Column want the same thing: to overthrow Anna.

Anna's plan to destroy the human soul did not go the way she had planned. But now she has the ability to mind control the human race... at what cost? Seeing the damage it did to her to mind control only one human, why would Anna believe she could control millions at the same time?

Oddly enough, seeing the softer side of Anna when she nestled Ryan's baby girl made me uneasily like her. Who knows? As doubtful as it would be, maybe Anna's human, emotional side will be able to defeat what I believe to be the bigger evil: Diana.

I was surprised to not see more awkwardness or sparks flying between Erica and Kyle. All we got was a brief moment when they talked about what happened the night before. I can't be the only one wanting to see more passion.

At first, I wasn't sure if I even liked Kyle, but after he  was able to calm Erica down, I fell in love with the guy. There may be a dark secret side to him, but who doesn't love a man with an edge... and an accent.

Joshua was the highlight of the episode because he saved Lisa and, in turn, got his memory back. This was huge for the Fifth Column because out of all the Visitors, Joshua was the most trustworthy. He had already proved his loyalty to the human race by risking his life to end Anna's plan and I don't doubt for a second that he would do it again.

By far the best episode of not only the season, but the series. There is so much to look forward to in the season finale that I fear it will be anticlimactic.
