They've entered the employee only area

Following Vasquez into what seems to be the employee area, a long hallway with a stairway at the far end and several exits along it, it's quickly apparent that employees know their way around because it's completely devoid of any signs.

Turning around, Susan raises an eyebrow at Supergirl "So, can you see or hear anything indicating where we should go?"

Taking a quick look around, Supergirl frowns "Um... the club is rather noisy, and most anything else I manage to catch is... well... people having sex? I think so anyway, and this whole warehouse seems to be from back when they used lead paint everywhere so I can't really see anything clearly, at most I can see shadows through some walls."

Shrugging at that response, Vasquez turns turns back towards the hallway "Well, let's head towards the end with the stairs and see if we find anything of interest, you're the lookout... or hearout I guess"

"Sure, I can do that!" as they start walking down the hallway Supergirl does a quick look through each doorway or in the case of the closed ones, through the doors themselves.

They've gotten almost all the way to the end when Supergirl suddenly exclaims "Stop!" next to a closed steel door "Ok, this one is... different. All the other rooms or hallways were utilitarian in a warehouse or club like fashion, but down here it's more of a... hospital feel? Everything is white and sterile and I see a bed on wheels next to one of the doors down there. There's also some stairs going down at the far end there."

Pulling out her lock picks Susan quickly finagles the lock open "Ok, before I open this, are there any people down there?"

Tipping her head to the side like some sort of puppy, Supergirl looks focused for a few seconds before shrugging "No one awake at least, there's a few heartbeats that are so slow that I'd not be surprised if they are in a coma or something."

Nodding at this, Vasquez carefully opens the door and leads the other woman through, closing it again behind them "Ok, I agree, this does indeed look more like a hospital or a lab than a club, let's explore a bit. Tell me the millisecond you feel even the hint of Kryptonite though, ok? No trying to be though."

"Oh don't worry, if I feel it, you'll know it."

In the control room, a guard presses a button connecting them to the boss "Ma'am, the sensor in Lord's lab triggered with the same power signature as earlier, this time we got it on video.
It's someone in a Supergirl costume that from these readings probably is the real deal, with a short haired chick in a leather jacket that seems to be in charge. What do you want us to do?"

The response is swift and comes out in a rather angry voice "First you'll hope to any god you believe in that our noise canceling works and she didn't hear that, then you'll leave them to me."
