The Book - The Flash Season 2 Episode 21

There's the book again. Will it act as his tether to the world to which he needs to return?

Holding Hands - The Flash Season 2 Episode 21

This is something we've never seen with our real Barry and Iris. Maybe being inside the speed force (if that's where he is) will do Barry some good. If he actually gets the girl, will he really want to come back?
Added:

Appealing - The Flash Season 2 Episode 21

Iris seems to be appealing to Barry. Oh, to be a fly on the camera when this was shot. Then again...spoilers!
Added:

Umbrella Love - The Flash Season 2 Episode 21

Is there anything more romantic than sharing an umbrella with the woman you love? Well, maybe if it IS the woman you love. This is probably NOT Iris.
Added:

Graveside - The Flash Season 2 Episode 21

Barry has a graveside seat to the news that somebody didn't make it. Will it be his own grave or his mother's or...really, I have no idea. You?
Added:

Time to Meet Not-Dad - The Flash Season 2 Episode 21

Let's keep up with the assumption that nobody is who they seem, and this is not Henry Allen. What will this ghost of the speed force have to say?
Added:

The Runaway Dinosaur - The Flash Season 2 Episode 21

This is the scene after which the episode is named, "The Runaway Dinosaur." It must have been a book Barry liked as a child.
Added:

Touching - The Flash Season 2 Episode 21

What are the odds we will cry at least once during these scenes between Barry and probably-not-Nora?
Added:

Not-Nora - The Flash Season 2 Episode 21

Assuming this isn't Nora, what sage advice will she have to give the man who isn't her son? It's going to be a long wait for Tuesday!
Added:

Confused - The Flash Season 2 Episode 21

Barry looks very confused. If he's confused, imagine how we'll be as this all plays out. Who cares? An emotional Barry is always gripping!
Added:

His Mother's Arms - The Flash Season 2 Episode 21

Barry is back in his mother's arms. But if Joe isn't Joe, then it's more than likely this isn't Nora Allen, either. Is Barry trapped inside the speed force? And what makes it so different?
Added:

Familiar Scene - The Flash Season 2 Episode 21

Surely, Barry thinks this is a very familiar scene. It's similar to the one he faced when his mother was killed when he was 10.

The Flash Season 2 Episode 21 Quotes

I'm talking to the speed force. Isn't that like saying I'm talking to gravity, or light, or...?

Barry

Iris: Dad, do you really think he's a metahuman?
Joe: Well, he got zapped by the particle accelerator and he was unconscious. It was worth a shot.
Iris: I gave you that mug!
