Supergirl 2x9 "Supergirl Lives" Poll

I don't think she does know

She knows, but can't prove it.

I voted that she knows but think it's purposefully been left open to interpretation so that they can choose whether she does or not to best fit the story. She does seem pretty switched on though so I would be very surprised if she didn't know.

#ISTANDWITHMELANIE

Very well said.

Abdul Bhutta

I voted she knows. She's said some slightly veiled things to Kara that don't really make any sense if she doesn't. Plus, I typically think of the Cat situation the way Batman describes his relationship with Commissioner Gordon and Superman's relationship with Perry White in Hush. Essentially, Gordon's too good of a detective and Perry White's too good a newsman to not figure it out, but they look the other way and purposely keep themselves in the dark to an extent because admitting the truth would fundamentally change the relationship and negatively affect the mission.

Neil Prospect

She definitely knows

Nyree Sullivan

I believe she knows as whilst the MMH thing threw her off the trail for a bit when he was exposed publically she must've figured it out

She knows. I think the martian manhunter thing threw her for a while though.

Ryan O'Malley

Oh she definitely knows.

Supermonaman

I'm pretty sure she knows but doesn't want to say anything

Cameron Mason

Im sure she knows. She was smart enough to know that Barry is the Flash. Also did you guys know that Harley Quinn Smith (Kevin Smith's daughter) was in this episode. And that Kevin Smith directed this episode.

Mary Poppins Y'all

Yes she knows! People who spend a good amount of time with the characters they always figure it out.

She figured out the flash and he wears a mask it's not that hard

Noah im a broke bitch now so I'm gonna hide here at the $10 tier Llamas

I would be actually surprised if she didn't.

As Maggie said, the glasses don't do much

Andrew Kennedy

She has to know! I've been thinking that since last season.
