Cecile, I can explain.

[dramatic music]
- So then I thought well obviously, this can't be
an Iris doppelganger from another Earth
because doppelgangers don't exist anymore.
Because the Multiverse doesn't exist anymore.
Because Crisis blew it all up, right?
- Uh-huh. - Exactly.
So if that's true, who else do we know
that could be pretending to be Iris?
- I--what-- - Shapeshifters.
All right, so Everyman was my first suspect.
And Cisco's report show that he is alive post-Crisis.
Then I remembered something
that Breacher said about Plastoids.
Which made me realize,
there could be shapeshifting Martians on this Earth now.
This--this fake Iris
doesn't even have to be from our planet.
But then, it hit me that J'onn J'onzz would sense
if there was a Martian hidden among us,

to my biggest breakthrough yet.
Okay, Cecile, the night that this all started,
Iris left to investigate a story.
I analyzed her phone's GPS
and it shows that she went to McCulloch Tech.
Cecile, I think that something happened to Iris that night.

Her throwing me out.
The real Iris would never stop fighting for us.
- Okay, okay, um.
Sweetie.
Do you think that maybe-- just maybe--
you're feeling a little scared, you know.
Because your marriage is going through
a rough patch, and maybe,
what you need to do is just go see Iris.
- That's not Ir-- Cecile, look.
Do you know why my Speed Gauge is still glowing red?
It is because the moment
that I stepped out of the loft, I realized
Iris, the real Iris, my wife,
she is somewhere else.
Probably in danger.
And if that's true, I need my speed back.
My--my lightning, all my powers if I'm gonna save her.
