It's hard to guess, really, why Dr. Stein has been called in, or when. Maybe he's helping Barry determine when and how to get BACK IN TIME to his mother? Shiver me timbers!!
Barry prepares himself mentally to go into the containment cell. Darn if we aren't going to get any of the really good photos. The odds are all of these take place within about 5 minutes of the episode, so the guess in on for the good stuff.
Barry is going into the particle accelerator, which is probably where the man they knew as Harrison Wells, Eobard Thawne aka Reverse Flash is being contained. We have to assume he can be contained!
Yes, these have to be welcome back moments, because can you think of another time Eddie would be looking on at a moment like this between Barry and Iris with such warmth? Surely it's fleeting.
Cisco takes a turn rubbing the magic genie. Hey, if you think about it, having a friend like Barry is about as magical as it's going to get. Taking the time to remember how important your friends are is always a good idea.
We're guessing at the timeline here, but it looks like these photos are right after the fight with Reverse Flash and Barry is being welcomed home, safe and sound.
It's nice seeing Joe out of uniform, but also a little jarring. It's so out of character that you know something extraordinary is about to take place. He's just never at STAR Labs looking like this.
Joe and Barry have what will likely be another amazing father son chat about what's next for Barry after kicking the Reverse Flash's ass. What CAN be next? That's the entirety of The Flash finale, I'm sure.
