Winn made a comment in episode 2 I think that her super hearing had always allowed her to know just when Cat grant is coming up the elevator.
Or it could have been in episode 1 and he was like "how do you always do that?" I cannot recall.
I don't know if that's right, but it does make the most sense for me.
There was no connection as such with the random guy. She helps people but doesn't forge bonds with all of them.
Human For A Day
My first reaction when we realize Kara has lost her powers: "Give her a cold!"
They gave her a cold (darn, that sniffiling 10-year old on the bus) and a broken arm.
Now she at least has an inkling about what it's like to be a normal human being. Alex was enjoying that a little too much.
Before all hell breaks loose -- yup, perfect day for a day-off -- Kara gets poked and prodded at the DEO. I hope, they learned enough (until the next time she looses her strength).
So, when all hell does break loose, Kara's benched and she finds it hard to not being able to help as Supergirl, so when she walks into that store where the hold-up is taking place, she shows that it doesn't always requires brute force to solve a possibly deadly situation. Although, let's call it what it was -- sheer good luck!
And Jimmy gets another great shot to shoot.
I wonder if Max Lord ever does anything without any ulterior motives. Probably not.
In the meantime, a mindcontrolling alien has made use of the momentary loss of power to escape his aquarium and wreak havoc on the DEO base, which is therefore on lockdown. Since Alex doesn't trust Henk any longer, she's hellbend on joining him in finding Gem (?). And he's like, oh no you don't, you're staying put. Gem gets the better of the two red shirts and Henshaw disappears, only to reappear telling them the inhibitors are broke so he goes off alone again. No way josé!
Alex convinces Donovan to follow her out of the safe room, and into danger. Donovan goes down, and Henshaw finds Alex, drags her into a control room where she orders him to chain himself to the wall. And then proceeds to take on Gem on her own.
Kick-ass action ensues, but he bests her and then Henshaw swoops in and ... HOLY HANNAH!! Who is this guy?!?
At which point, he reveals himself to Alex and tells her about her father. And then there's a green martian standing there. .... and I'm like: WOW!! Cool!
