Man shark, land shark, hey, we see you!

The metahumans from Earth 2 are just a little different, and we see a pretty cool one on The Flash Season 2 Episode 4. But still no sign of Zoom. Zoom, Zoom, where are you? The Flash is definitely in need of a big bad.

Harrison Wells is not a big bad anymore. In fact, he may just have saved the life of The Flash! What a strange and mixed up world.

Professor Stein has a couple of candidates for his Firestorm matrix, thank goodness. One of these things is not like the other, however, and one of these things is full of fury. Will the team be able to determine which one is the right match in time for Stein to merge so he doesn't explode?

And what is the big secret Iris' mother is keeping? Trust us on this, it's a doozy that even Det. Joe West won't see coming.

Iris: I'm sure that you've been through a great deal, and I can appreciate you feeling like this is suddenly the right time to want me in your life, but that doesn't mean that it's the right time for me.
Joe: Iris...
Iris: No, dad, it's OK. I've thought about this a lot, and it wasn't fair for me to make you the bad guy. [turns to Francine] So I want you to hear this from me. I don't hate you, Francine. I do wish you well. But we have lived separate lives for over 20 years. Let's keep it that way.

Cisco: Awwww how cute! We'll have two Professor Steins if this works!
Caitlin: It's gonna work.
